# Math Review 10/12/16

### Math review for Test

What is the measurement of the exterior angle in the diagram? Look at Image 1. A:95 X=10
What series of transformation could have been used? Look at Image 2. A: Rotate 180 degrees OR Reflect over Y then Reflect over X OR Reverse the Two
What is the relationship Between 68 and angle 4 and angle 5? Look at Image 3. A:68, 4, and 5=180
If angle 4 is 75 what must be the measure of angle 3? Look at Image 3. A:Angle3=105
Find the measure of angle 5. Look at Image 3. A:Angle 5=37
Andrew constructed a triangle so that the measurement of angle1 and angle2 were congruent. If angle 3 measure 50 degrees, what is the measurement of angle 1? A:X=65
Triangle 1 and Triangle 2 are similar why? Look at Image 4. A:AngleC=26 AngleH=64
Triangle RST is the result of a sequence of transformations using the pre- image Triangle ABC. If the first transformation of the sequence was dilation about the origin, identify the scale factor. Look at Image 5. A:2
Using Image 6 find BE. A:X=4.5
In the Image 7, Lines A and B are parallel. A:X=59
The angle measures of a triangle are 2x+3 degrees, 4X+2 degrees, and 2X-1 degrees. Find x and find the measure of eac angle of the triangle? A:X=22 Measures:47,90,43
Which of the transformations would NOT preserve size and shape? A:Dilations
A triangle has vertices of A(-3,4),B(1,1), and C(2,3). Find the coordinates of the triangle if it is reflected over the Y-axis , and then dilated by a scale factor of 2. A:A. A'(3,4) B'(-1,1) C'(-2,3) B. A''(6,8) B''(-2,2) C''(-4,6)
Find The coordinates if the original triangle A(-3,4),B(1,1), and C(2,3) is dilated by a scale factor of 2 and then reflected over the y-axis. A:A. A'(-6,8) B'(2,2) C'(4,6) B. A''(6,8) B''(-2,2) C''(-4,6)
Identify the angel pair created in Image 8. A: Alternate Interior Angle
Find the value of X in Image 8. A:X=12
What is the measurement of A? Look at Image 9. A:A=105
Solve for X. Look at Image 9. A:X=15
What is the measurement of Y? Look at Image 9. A:Y=75
What is the measurement of X? Look at Image 10. A:X=50
What is the measurement of Y? Look at Image 10. A:Y=100
In triangle XYZ, YZ is parallel to PQ. Find the length of YZ. Look at Image 11. A:YZ=2
