Area of Triangles

Front

What is the formula for 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 the side on which the triangle stands.

Front

What is the height of a triangle?

Back

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

Front

How do you find the area of a triangle with a base of 10 units and a height of 5 units?

Back

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

Front

What is the area of a triangle with a base of 12 ft and a height of 10 ft?

Back

Area = 1/2 × 12 × 10 = 60 square feet.

Front

If a triangle has an area of 30 square units and a base of 6 units, what is the height?

Back

Height = (Area × 2) / base = (30 × 2) / 6 = 10 units.

Front

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

Back

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

Front

Can the base and height of a triangle be the same length?

Back

Yes, a triangle can have equal base and height, resulting in a specific area.

Front

What happens to the area of a triangle if the height is doubled?

Back

The area of the triangle will also double.

Front

What is a right triangle?

Back

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