Geometry | Unit 3 | Lesson 5: Splitting Triangle Sides with Dilation, Part 1 | Practice Problems

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 DEF are shown. What is the length of AB?

Draw 2 lines that could be the image of line m by a dilation. Label the lines n and p.

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 a.

Lin is using the diagram to prove the statement, “If a parallelogram has one right angle, it is a rectangle.” Given that EFGH is a parallelogram and angle HEF is a right angle, write a statement that will help prove angle FGH is also a right angle. Han then states that the 2 triangles created by diagonal EG must be congruent. Help Han write a proof that triangle EHG is congruent to triangle GFE.
