Understanding Angles and Protractors

Dominique's homework involves measuring angles in her house using a protractor. She starts by measuring the angle of a window corner, which is 90 degrees, and then measures an angle on a Vaz, which is 120 degrees. Dominique then needs to draw these angles to show her teacher, using the protractor to draw lines and mark points accurately.

What is the total number of degrees a protractor can measure from one side to the other?

• 90 degrees

• 180 degrees

• 270 degrees

• 360 degrees

What angle did Dominique measure at the corner of her window?

• 90 degrees

• 120 degrees

• 60 degrees

• 45 degrees

Which object in the living room had an angle of 120 degrees?

• The window

• The table

• The door

• The vase

What is the first step Dominique takes to draw an angle using a protractor?

• Measures the angle

• Marks a point at the desired angle

• Draws a line with the protractor

• Aligns the protractor with the edge

Where does Dominique mark a point to draw a 90-degree angle?

• At the 45-degree mark

• At the 60-degree mark

• At the 120-degree mark

• At the 90-degree mark

After marking the point, what does Dominique do next to complete the angle?

• Draws a circle

• Draws a line up to the point

• Erases the line

• Measures the angle again
