Shape Up!
Type of triangle with all sides and angles congruent
What is equilateral?
If the central angle of a circle is 70 degrees, the intercepted arc is this size
What is 70 degrees?
Side lengths of a 45-45-90 triangle
The legs are the same length and the hypotenuse is the leg length times the square root of 2.
This is true about the slopes of perpendicular lines
They are negative reciprocals
How to calculate arclength
Circumference (2 pi r) times degrees in arc divided by 360
Shape with four congruent sides
What is a rhombus?
The name of the angle pairs formed when two lines cross
What are vertical angles?
Side lengths of a 30-60-90 triangle
The hypotenuse is twice as long as the shortest side and the medium side is the short side times the square root of 3. (x, 2x, x times square root of 3)
Parallel lines have the same
What is slope?
The area of a circle.
What is pi x r squared?
Shape with two pairs of consecutive congruent sides
What is a kite?
The word meaning, "adds up to 180 degrees"
What is "supplementary"?
Common Pythagorean Triplet
3-4-5 or 5-12-13
How you find the distance between two points on the coordinate plane
What is, "calculate the distance between the x-values and the distance between the y-values and use in the Pythagorean Theorem"?
The circumference of a circle
What is pi X d or 2(pi)r?
Shape with four sides
What is a quadrilateral?
What are the three ways to prove two triangles are congruent?
ASA, SAS, SSS
The word describing the relationship between the two acute angles in a right triangle
What is "complementary"?
What is true about corresponding angles?
They are congruent.
Draw a shape with 4 sides but only 1 pair of parallel sides.
Picture of Trapezoid
If an inscribed angle is 40 degrees, how big is the intercepted arc?
80 degrees
Use this to find the missing side of a right triangle when two side lengths are known.
What is the Pythagorean Theorem?
How you find the midpoint of a line
What is "find the averages the x-coordinates and the y-coordinates"?
What does the linear pair Theorem state?
If two angles form a linear pair, then they are supplementary.
