All About Triangles

100

How many degrees does a triangle have?

180 degrees

200

A triangle has one angle of 90°. What type of triangle is it ALWAYS?

Right triangle

300

A triangle has angles of 45° and 60°. What is the missing angle?

75°

400

A triangle has angles measuring 50°, 60°, and 70°. Is this possible? Explain.

Yes it is possible because they add up to 180°.

500

Can a triangle have angles of 100°, 50°, and 40°? Why?

No, they add to 190°.

Name That Angle

100

What is one example of a degree measure for an obtuse angle?

Anything above 91 degrees

200

What type of angle measures 2°?

Acute angle

300

• What type of triangle has no equal sides?

• Which triangle has all sides different lengths?

• A triangle with three unequal sides is called what?

• What do you call a triangle where no sides are the same length?

Scalene triangle

400

If all angles in a quadrilateral are equal, what is the measure of each angle?

90°

500

A triangle’s angles are in a pattern: one angle is 10° more than another, and the third is 20° more than the smallest. Find all angles

50°, 60°, 70°

Random

100

A triangle has a total of 180 degrees. A quadrilateral also has a total of 180 degrees. 

No, there are 360 degrees in a quadrilateral 

200

A scalene triangle must have what

All sides with different lengths

300

Adventure

400

A trapezoid has angles measuring 70°, 110°, and 80°. What is the missing angle?

100°

500

If you split a quadrilateral into two triangles, what does this help prove about angle sums?

That they add to 360° (180° + 180°).

All About Quadrilaterals

500

A quadrilateral has no parallel sides. What type could it be?

Irregular quadrilateral; kite
