What is a triangle?

Back

A triangle is a polygon with three edges and three vertices. It is one of the basic shapes in geometry.

Front

What is the Triangle Inequality Theorem?

Back

The Triangle Inequality Theorem states that the sum of the lengths of any two sides of a triangle must be greater than the length of the third side.

Front

What is a midsegment in a triangle?

Back

A midsegment is a line segment that connects the midpoints of two sides of a triangle. It is parallel to the third side and half its length.

Front

How do you find the length of a missing side in a triangle?

Back

Use the Pythagorean theorem for right triangles or the Triangle Inequality Theorem for other types of triangles.

Front

What are the properties of an equilateral triangle?

Back

An equilateral triangle has all three sides equal in length and all three angles equal to 60 degrees.

Front

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

Can a triangle have two right angles?

Back

No, a triangle cannot have two right angles because the sum of the angles would exceed 180 degrees.

Front

What is the formula for the area of a triangle?

Back

The area of a triangle can be calculated using the formula: Area = 1/2 * base * height.

Front

What is a scalene triangle?

Back

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

Front

What is a right triangle?

Back

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