Ordering Sides and Angles in Triangles

Front

What is the sum of the angles in a triangle?

Back

The sum of the angles in a triangle is always 180 degrees.

Front

If angle A is 30 degrees and angle B is 60 degrees, what is angle C?

Back

Angle C is 90 degrees (180 - 30 - 60 = 90).

Front

In triangle ABC, if angle A is the largest angle, which side is the longest?

Back

Side BC is the longest side.

Front

What is the relationship between the angles and sides of a triangle?

Back

In a triangle, the larger the angle, the longer the opposite side.

Front

If two angles in a triangle are equal, what type of triangle is it?

Back

It is an isosceles triangle.

Front

What is an acute triangle?

Back

An acute triangle is a triangle where all three angles are less than 90 degrees.

Front

What is a right triangle?

Back

A right triangle is a triangle that has one angle equal to 90 degrees.

Front

What is an obtuse triangle?

Back

An obtuse triangle is a triangle that has one angle greater than 90 degrees.

Front

How do you identify the longest side in a right triangle?

Back

The longest side in a right triangle is called the hypotenuse, which is opposite the right angle.

Front

What is the formula to find the area of a triangle?

Back

Area = 1/2 * base * height.
