Geometry & Measurement Practice

Which angle is obtuse?

• 47°

• 164°

• 183°

• 91°

• 360°

Perimeter measures the

• Space inside of a geometric shape

• Length of a one dimensional (1D) shape

• Area inside a two dimensional (2D) shape

• Distance around a geometric shape

The formula for the area of a triangle is

• base X height/2

• 1/2 (base X height)

• length X width

• base X height X 2

• (a + b)h/2

This shape is called a

• Parallelogram

• Isosceles triangle

• Rectangle

• Trapezoid

• Diamond

The area of this shape is calculated using the formula

• base X height

• b X h

• base X height/2

• (a + b) h/2

Calculate the area of the triangle.

• 20 cm

• 10cm²

• 12 cm

• 6 cm²

• 6cm

Calculate the perimeter of the triangle

• 12 cm²

• 6 cm²

• 12 cm

• 6 cm

• 10cm

Calculate the area of the triangle

• 30cm²

The interior (inside) angles of a triangle add up to

• 45°

• 90°

• 180°

• 360°

• 480°

This angle is

• acute

• obtuse

• straight

• right

• isosceles
