Question

In the diagram, $\overleftrightarrow{AB}\perp \overleftrightarrow{CD}$and $\overleftrightarrow{EF}\perp \overleftrightarrow{GH}$. Name eight right angles.

Short answer

The required angles are$\angle AOC$, $\angle AOD$, $\angle BOC$, $\angle BOD$, $\angle EOG$, $\angle EOH$,$\angle FOG$ and$\angle FOH$.

Step-by-step solution

Step 1. Definition of the right angle.

Basically angles having the measurement of 90ۜ° are referred to as the right angles these angles are from the perpendicular relation between two lines.

Step 2. Determine the required angles.

Extract all the points which are 8 in count from the given lines that are having perpendicular relation between them.

$\angle AOC$, $\angle AOD$, $\angle BOC$, $\angle BOD$, $\angle EOG$, $\angle EOH$,$\angle FOG$ and $\angle FOH$.

Step 3. Make the conclusion.

As the angles $\angle AOC$, $\angle AOD$, $\angle BOC$, $\angle BOD$, $\angle EOG$, $\angle EOH$,$\angle FOG$ and$\angle FOH$ are related with the given lines so these are the required angles.
