I need help with geometry... anyone?
1] If m2] If x+3=17, then x=14. 3] xy = yx 4] If 7x = 42, then x = 6. 5] If XY - YZ = XM, then XM + YZ = XY. 6] 2(x+4) = 2x + 8 7] If m Now, those are all proofs. We can use these word(s)/reasons; -segment addition postulate -segment congruence postulate -angle addition postulate -angle congruence postulate -linear pair property -vertical angles are congruent -def. of complementary angles -def. of supplementary angles -def. of a segment bisector -def. of perpendicular lines -def. of a perpendicular bisector -def. of a midpoint -def. of an angle bisector -addition -subtraction -multiplication -division -distributive -substitution -transitive -reflexive -symmetric -simplify -factor -zero product property -def. of a right angle def. = definition I have all the answers, I just dont know if they are right. So if ANYONE! could just do it really quickly, thatd be amazing. :) izzy.
I need help with Geometry proofs?
may be ? is incomplete or wrong
I need help with this geometry problem?
Circumcenter. When you find the perpendicular bisector of each sides of a triangle, the point where they all intersect is the center of the circle.
I need help with geometry question?
Let A = the bigger angle; B = the smaller angle A + B = 90 degree ( A and B are complementary angle) Sum = A + B Difference = A - B A + B = ( A - B ) + 30 degrees (sum exceeds difference by 32 degrees) A + B = A - B + 32 2B = 32 B = 16 A + B = 90 A + 16 = 90 A = 90-16 = 74 The bigger angle (A) is 74 degrees; The smaller angle (B) is 16 degrees
I need help with some Geometry homework!?
OK, here's the problem. The graphs of each group of equations have at least one characteristic in common. Name the characteristics and then graph each group of equations on the same axes. Then write an additional equation for each group that shares the characteristics you have named. A. y=x, y=3x, y=5x B. y=2x, y=2x +1, y=2x-3 C. 2y=6x, 4y-12x=0, 3x-y=0 D. 2x-4y=12, 3y+2x= -2, x+y=0
Geometry problem I need help with?
The surface area of a cube is 600cm^2 What is the new surface area of the cube if the length of each edge of the cube is tripeled? The answer is 5400^2 but I'm not sure how this is the answer??
Do you need algebra 1 to do geometry and do you need geometry to do algebra 2?
You definitely need Algebra 1 to do Geometry, as you do need to know how to solve for variables and graph basic equations for Geometry so you can find certain features of graphs or find the sides or volume of a shape.However, you don’t necessarily need Geometry for Algebra 2. I did them at the same time, and while at times Geometry concepts would come up in Algebra 2 that I didn’t know, my teacher would end up going over them again anyway because no one remembered it from Geometry, so I was fine.It depends on the school though. My school does Geometry before Algebra 2 (unless you double up like I did), but some do Algebra 2 before Geometry. Some schools allow you to double up, some don’t. Check the prerequisites for the classes at your school and check to see if they allow doubling up, and that’ll answer your question. If you can double then you don’t need Geometry for Algebra 2 and vice versa at your school, but if you can’t then your school set it up so you need one before the other.
I need Geometry Help...Find the geometric mean of the pair of numbers.?
Ughgh I dont know how to do these.... i have been trying forever... my older sister said these are easy but she wont show me....so i dont think she really knows. pleaseeee someone help me. Find the geometric mean of the pair of numbers. 1. 175 and 7 a. 55 b. 45 c. 35 d. 40 2. 5 and 6 a. 30 b. 6 c. /35 d. /30
I need help with my Geometry homework? Constructing perpendicular and angle bisectors...?
_______________________________ Rather than trying to talk you through constructing the triangles with the bisectors, which would be quite difficult to do, let me talk you through how to construct an angle bisector and a perpendicular bisector. Angle Bisector 1) Construct angle ABC with vertex B. 2) With your compass on point B, strike an arc across both rays of the angle. Label the points of intersection D and E. 3) With you compass on point D, strike an arc between rays BA and BC and furthest away from B. Now, without changing your compass setting, do the same from point E. Label the point where the two arcs intersect point F. 4) Construct line segment BF. BF is the angle bisector of angle ABC. ________________________________ Perpendicular Bisector of a line segment 1) Horizontally, construct line segment AB. 2) With your compass on point A, strike an arc above and below, roughly, the midpoint of AB. Now, without changing your compass setting, do the same from point B. 3) Label the points of intersection C and D. Construct the line segment CD. CD is the perpendicular bisector of line segment AB. There's what you need to construct the bisectors for the triangles. Now, for your other questions: 1) The perpendicular bisector of a side of a triangle is (sometimes) the angle bisector. 2) The angle bisectors of a scalene triangle (always) intersect at a single point. I believe this is correct. But, I'm not 100% sure. 3) The angle bisectors of a right triangle (always) intersect inside the triangle. 4) The perpendicular bisectors of the sides of a right triangle always intersect at the midpoint of the hypotenuse. Question for you: Is that considered inside the triangle? Hope that helped. ______________________________________...
