Angle Relationships
The sum of two supplementary angles equals this many degrees.
What is 180?
This is the longest side of a right triangle, located opposite the right angle.
What is the hypotenuse?
This geometric transformation slides a figure to a new position without turning or resizing it.
What is a translation?
This 3D shape has a circular base that tapers to a single point at the top.
What is a cone?
Two figures are this if they have the exact same shape and the exact same size.
What is congruent?
These types of angles are opposite each other when two lines intersect and are always equal
What are vertical angles?
This is the missing length of a right triangle's hypotenuse if the legs measure 3 inches and 4 inches.
What is 5 inches?
This type of transformation flips a figure over a line, creating a mirror image.
What is a reflection?
To find the volume of this perfectly round 3D object, you multiply four-thirds by pi by the radius cubed.
What is a sphere?
Two figures are this if their corresponding angles are equal and their corresponding side lengths are proportional.
What is similar?
When a transversal crosses parallel lines, these angles lie on opposite sides of the transversal and inside the parallel lines.
What are alternate interior angles?
his is the formula used to find a missing side length in any right triangle.
What is a^2+b^=c^?
This is the only transformation covered in 8th grade that changes the size of the original figure.
What is a dilation?
This is the volume of a cylinder with a radius of 2 inches and a height of 5 inches, using 3.14 for pi.
What is 62.8 cubic inches?
This transformation always results in a similar figure, but not a congruent one.
What is a dilation?
If Angle A and Angle B are complementary, and Angle A is 35 degrees, this is the measure of Angle B.
What is 55 degrees?
This is the length of a leg if the hypotenuse of a right triangle is 13 cm and the other leg is 5 cm.
What is 12 cm?
If the point (-2,3) is reflected across the x-axis, these are the coordinates of the new point.
What is (2,3)?
If a cylinder and a cone have the exact same radius and height, the cone's volume is this fraction of the cylinder's volume.
What is one-third?
A 6-foot tall man casts a 4-foot shadow. At the same time, a nearby tree casts a 20-foot shadow. This is the height of the tree.
What is 30 feet?
This is the value of x if two vertical angles measure (3x+10) and (2x+30) degrees.
What is 20?
To the nearest whole number, this is the distance between the coordinate points (1,2) and (4,6).
What is 5?
A triangle is dilated by a scale factor of 0.5. If the original perimeter is 24 cm, this is the new perimeter.
What is 12 cm?
This is the volume of a cone with a radius of 3 cm and a height of 4 cm, using 3.14 for pi.
What is 37.68 cubic cm?
f Triangle ABC is similar to Triangle DEF, and the side lengths of DEF are 3 times larger, this is the ratio of their areas.
What is 1 to 9?
