Solve each equation.
1.x + 6 = 25 2. x + 7 + 13 = 33
3.5x = 540 4. x + 10 = 2x
5.For the triangle at the right, use the Triangle
Angle-Sum Theorem to find the value of y.

Congruent figures have the same ______________ and _______________.
When two figures are congruent, you can move one so that it fits exactly on the other one.
![Page 5: Congruent Figures Section 4-1. Solve each equation. 1.x + 6 = 252.x + 7 + 13 = 33 3.5x = 5404.x + 10 = 2x 5.For the triangle at the right, use the Triangle](https://reader035.vdocuments.us/reader035/viewer/2022070307/551ada2b55034606048b55ba/html5/thumbnails/5.jpg)
Three ways to make such a move are a _____________, a _____________, or a ________________.

Discovery Learning:
1. Draw a shape on your paper.
2. Cut it out. Trace the original shape on the paper again.
3. Flip/slide/rotate the shape and trace it.
4. Draw both the original shape and the “new” shape on the board.
5. As a class, figure out how each shape was flipped/slid/rotated.
