Here are questions about two types of angles.
- Draw a right angle. How do you know it's a right angle? What is its measure in degrees?
- Draw a straight angle. How do you know it’s a straight angle? What is its measure in degrees?
An equilateral triangle’s angles each have a measure of 60 degrees.
Can you put copies of an equilateral triangle together to form a straight angle? Explain or show your reasoning.
Can you put copies of an equilateral triangle together to form a right angle? Explain or show your reasoning.
Here is a square and some regular octagons.
In this pattern, all of the angles inside the octagons have the same measure. The shape in the center is a square. Find the measure of one of the angles inside one of the octagons.
The height of the water in a tank decreases by 3.5 cm each day. When the tank is full, the water is 10 m deep. The water tank needs to be refilled when the water height drops below 4 m.
