REVIEW for TEST on Geometry Part 2

Front

What is the formula for the surface area of a triangular prism?

Back

Surface Area = (Base Area x 2) + (Perimeter of Base x Height)

Front

How do you calculate the perimeter of a triangle with sides of lengths 3 m, 4 m, and 5 m?

Back

Perimeter = 3 m + 4 m + 5 m = 12 m

Front

What is the Pythagorean theorem?

Back

In a right triangle, a² + b² = c², where c is the hypotenuse.

Front

If a triangle has a base of 4 m and a height of 3 m, what is its area?

Back

Area = 1/2 x base x height = 1/2 x 4 m x 3 m = 6 m²

Front

What is the formula for the diagonal of a rectangle?

Back

Diagonal = √(length² + width²)

Front

How do you find the surface area of a rectangular prism?

Back

Surface Area = 2(lw + lh + wh), where l = length, w = width, h = height.

Front

What is the relationship between the sides of a 30-60-90 triangle?

Back

The sides are in the ratio 1 : √3 : 2.

Front

How do you calculate the area of a trapezoid?

Back

Area = 1/2 x (Base1 + Base2) x height.

Front

What is the formula for the circumference of a circle?

Back

Circumference = 2πr, where r is the radius.

Front

If the radius of a circle is 5 cm, what is its area?

Back

Area = πr² = π(5 cm)² = 25π cm².
