Congruent Figures Section 4-1

3
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 Angle-Sum Theorem to find the value of y.

4
Congruent figures have the same ______________ and _______________. When two figures are congruent, you can move one so that it fits exactly on the other one.

5
Three ways to make such a move are a _____________, a _____________, or a ________________.

6
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.
