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 one angle in a triangle is 90 degrees, what type of triangle is it?

Back

It is a right triangle.

Front

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

Back

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

Front

How do you order the angles of a triangle from smallest to largest?

Back

Order the angles based on their measures; the smallest angle corresponds to the shortest side.

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 an obtuse triangle?

Back

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

Front

What is a scalene triangle?

Back

A scalene triangle is a triangle where all three sides and all three angles are different.

Front

What is an isosceles triangle?

Back

An isosceles triangle is a triangle that has at least two sides of equal length.

Front

What is an equilateral triangle?

Back

An equilateral triangle is a triangle where all three sides and all three angles are equal.

Front

How can you determine the longest side of a triangle?

Back

The longest side is opposite the largest angle.
