Chapter 4: Q16. (page 119)

The pentagons shown are congruent. Complete.
If $\bar{CA} ⊥ \bar{LA},$ name two right angles in the figures.

Short Answer

Expert verified

The two right angles in the figures are $∠ CAL$ and $∠ EHO$ .

Step by step solution

Step 1. Observe the given diagram.

The given diagram is:

Step 2. Description of step.

The given pentagons are congruent.

Therefore, corresponding angles and corresponding sides of pentagons will be equal.

- Write the conclusion.

From the given diagram it can be noticed that the corresponding angles for the angles $B, L, A, C$ and $K$ are the angles $R, O, H, E$ and $S$ respectively.

Therefore, as $\bar{C A} ⊥ \bar{L A},$ it can be said that $\bar{E H} ⊥ \bar{O H} .$

Therefore, the two right angles in the figures are $∠ C A L$ and $∠ E H O .$
