IM Geo.3.5 Practice: Splitting Triangle Sides with Dilation, Part 1
What is the measure of angle A'B'C?
Triangle DEF is formed by connecting the midpoints of the sides of triangle ABC.
The lengths of the sides of are shown. What is the length of ?
There is an angle ABC.
It is taken by a dilation with center and scale factor to angle . The measure of angle is . What is the measure of angle ?
Draw 2 lines that could be the image of line m by a dilation.
Label the lines and .
Is it possible for polygon ABCDE to be dilated to figure VWXYZ?
Explain your reasoning.
Triangle XYZ is scaled and the image is X'Y'Z'.
Write 2 equations that could be used to solve for .
Lin is using the diagram to prove the statement, “If a parallelogram has one right angle, it is a rectangle.”
Given that is a parallelogram and angle is a right angle, write a statement that will help prove angle is also a right angle.
Han then states that the 2 triangles created by diagonal must be congruent. Help Han write a proof that triangle is congruent to triangle .
