Show transcript
The area of a triangle is half the area of a parallelogram with the same perpendicular base and height.
The area of a triangle can be calculated using the formula area = base × perpendicular height ÷ 2
A missing perpendicular height in a triangle can be found using the formula area × 2 ÷ base
A missing base in a triangle can be found using the formula area × 2 ÷ perpendicular height
