Question

5 mark for review triangles efg and jkl are congruent, where e, f, and g correspond to j, k, and l, respectively. the measure of angle e is 45° and the measure of angle f is 20°. what is the measure of angle j? a 20° b 45° c 135° d 160°

Explanation:

Step1: Recall congruent - triangle property

Corresponding angles of congruent triangles are equal.

Step2: Identify corresponding angles

Since $\triangle EFG\cong\triangle JKL$ and $E$ corresponds to $J$, $\angle E=\angle J$.

Step3: Substitute the value of $\angle E$

Given $\angle E = 45^{\circ}$, so $\angle J=45^{\circ}$.

Answer:

B. $45^{\circ}$
