What you really need to know!
What you really need to know!
If two triangles are congruent, their corresponding sides are congruent and their corresponding angles are congruent.
Example 1:
Name the corresponding pairs in the congruent triangles shown. Then complete the congruence statement.
D H, E G, F I, DE HG, DF HI, EF GI, ∆HGI ∆DEF
Example 2:
If ∆MNO ∆QPR, complete each congruence statement.
M ??P ??O ??QP ??NO ??MO ??
M QQP N N O R R QP MN MN NO PR PR MO QR QR
Example 3:
A brace is used to support a tabletop. In the figure ∆ABC ∆DEF.
What is the measure of F?
F C, so F is 50°.
What is the length of DF?
DF AC, so DF is 2 ft.
