Area
Area of a rectangle with a base of 4 meters and a height of 20 meters.
What is 80 square meters.
This line runs through the center of a circle and extends from one end to another
What is the diameter?
A right angle measures this many degrees
What is 90 degrees
Angles that have a sum of 180 degrees are known as
What are supplementary angles
Find the area of a rectangle using this formula.
What is length x width (or base x height)?
Area of a triangle with a base of 5 mm and a height of 4 mm.
What is 10 square mm.
A delicious dessert or the ratio of a circle's circumference to its diameter
What is pi
2 lines that run equidistant and never intersect.
What are parallel lines?
Angles that directly across from each other are congruent, and also
What are vertical angles
The formula for area of a parallelogram is similar to that of a rectangle, but the dimensions don't quite have the same names.
What is base x height
You need these two dimensions to find the area of a parallelogram, a trapezoid, and a triangle
What are base and height
Polygons have perimeter to describe the distance around them. Circles have this instead.
What is circumference?
Lines that intersect on a right angle.
What are perpendicular lines?
A little square lets you know that you have this type of angle
What is a right angle
A triangle's area is the same as that of this shape, just cut in half.
What is a square/rectangle
Given a diameter of 10 cm, the area of a circle would be this size.
What is 78.5 square cm
This measure is used to find the area of a circle. It is also half of the diameter.
What the radius
An angle that is greater than 90 degrees but less than 180 degrees.
What is an obtuse angle?
If an angle is 67 degrees, its complementary angle would be this amount
What is 23 degrees
Area of a triangle.
What is base times height divided by 2? (OR What is 1/2 x base x height?
The area of a triangle is 30 cm, with a height of 6 cm. All you are missing is a base of this size.
What is 10 cm.
Finding the circumference of a circle is as easy as
pi x diameter or pi x radius x 2
These angles are neighbors and share a line
What are adjacent angles
Given an angle with a measure of 2x +5 and another with a measure of 3x, and given that they are supplementary, the value of each angle would be
What is 105 and 75 degrees
Area of a trapezoid
(base + base) * height * (1/2)
