Question

Given the diagram, tell whether you can reach the conclusion shown.

Name a right angle.

Short answer

The required angle is$\angle DAB$.

Step-by-step solution

Step 1. Symbol that can be used to represent right angle.

The angle that is a right angle contains a small square on it because this is the representation of right angle.

Step 2. Make an observation from the given figure.

The figure contains only one angle that contains a small square on it that is the $\angle DAB$which represents that $\angle DAB$is the right angle.

Step 3. Make the conclusion.

In the figure, except $\angle DAB$none of the angle contains the small square which means that the required angle is $\angle DAB$.
