What is the sum of the interior angles of a triangle?

Back

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

Front

Define a scalene triangle.

Back

A scalene triangle is a triangle in which all three sides are of different lengths.

Front

What is an equilateral triangle?

Back

An equilateral triangle is a triangle in which all three sides are equal in length and all three angles are equal to 60 degrees.

Front

Define an acute triangle.

Back

An acute triangle is a triangle in which 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 measuring 90 degrees.

Front

How do you determine the type of triangle based on its angles?

Back

You can determine the type of triangle based on its angles by measuring the angles: if all angles are < 90°, it's acute; if one angle = 90°, it's right; if one angle > 90°, it's obtuse.

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

Back

In a triangle, the largest angle is opposite the longest side, and the smallest angle is opposite the shortest side.
