Area of Triangles

Front

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

Back

Area = 1/2 × base × height

Front

What is the base of a triangle?

Back

The base is one side of the triangle, often considered the bottom side when the triangle is drawn.

Front

What is the height of a triangle?

Back

The height is the perpendicular distance from the base to the opposite vertex.

Front

If the base of a triangle is 10 units and the height is 5 units, what is the area?

Back

Area = 1/2 × 10 × 5 = 25 square units.

Front

What is a right triangle?

Back

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

Front

What is an equilateral triangle?

Back

An equilateral triangle is a triangle where all three sides are of equal length.

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 a scalene triangle?

Back

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

Front

How do you find the height of a triangle if you know the area and the base?

Back

Height = (2 × Area) / base.

Front

What is the relationship between the base and height in calculating the area of a triangle?

Back

The area of a triangle is directly proportional to both the base and the height.
