Q12WE. - Geometry

Question

If you measure $\mathbf{\angle }\mathbf{EFG}$ with a protractor you get more than $\mathbf{90}\mathbf{°}$. But you know that $\mathbf{\angle }\mathbf{EFG}$ 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.
