Congruent Equations

What can you conclude?

• AB and AC are not congruent.

• AB= half of AC

• AC = half of AB

• AB=AC

Write an equation that correctly models the lengths shown.

• 2x + 20 + x + 21 = 9

• 2x + 20 + 9 = x + 21

• 9 + x + 21 = 2x + 20

• 2x + 20 - 9 = x + 21

Solve for x.

• x = 5 

• x = 20

• x = 3
