Q12 - Geometry

Question

If you measure $\angle EFG$ with a protractor you get more than $90°$. But you know that $\angle EFG$ represents a right angle in a box. Using this as an example, complete the table.

Step-by-Step Solution

Answer

	$\angle EFG$	$\angle AEF$	$\angle DCB$	$\angle FBC$
In the diagram	Obtuse	Right	Acute	Obtuse
In the box	Right	Right	Right	Right

Step 1. Observe the diagram.

The given diagram is:

Step 2. Find the angle AEF in the diagram and in the box.

From the diagram, it can be noticed that the angle AEF in the diagram is a right angle and the angle AEF in the box is a right angle.

Step 3. Find the angle DCB in the diagram and in the box.

From the diagram, it can be noticed that the angle DCB in the diagram is an acute angle and the angle DCB in the box is a right angle.

Step 4. Find the angle FBC in the diagram and in the box.

From the diagram, it can be noticed that the angle FBC in the diagram is an obtuse angle and the angle FBC in the box is a right angle.
