Chapter 4.1, Problem 16CE

To determine

To Find : Find the two right angles in the given figure.

Answer to Problem 16CE

  $\angle CALand\angle EHO$

Explanation of Solution

Given information : The given pentagon is congruent as shown in figure

Given that the pentagon is congruent.

So their corresponding sides and angles are congruent.

So we must have

  $B\leftrightarrow R$ , $L\leftrightarrow O$ , $A\leftrightarrow H$ , $C\leftrightarrow E$ , $K\leftrightarrow S$

Since $\overline{CA}\perp \overline{LA}$

So, we also have

  $\overline{EH}\perp \overline{OH}$

Therefore, the two right angles are

  $\angle CALand\angle EHO$
