Parallel Lines/Transversal
These two angles lie on opposite sides of the transversal and inside the parallel lines; they are always congruent.
This is the constant sum of the interior angles of any triangle, whether it is acute, obtuse, or right.
180
In the formula a^2 + b^2 = c^2, the variable c always represents this side, the longest side of a right triangle.
hypotenuse
Express the number 0.000045 in scientific notation.
4.5 x 10^-5
Since a full circle is 360, an angle that measures 90 represents this common fraction of a circle.
1/4
When a transversal cuts parallel lines, these angles are down the transversal from each other, and congruent
Corresponding
In an equilateral triangle, this is the degree measure of each individual interior angle.
60
This is the missing side length of a right triangle with legs of 3 and 4.

Convert 8.2 x 10^6 into standard notation.
8,200,000
This is the degree measure of an angle that represents exactly 1/2 of a circular rotation.
180
Consecutive Interior angles have this numerical relationship.
supplementary or add up to 180
According to the Exterior Angle Theorem, the measure of an exterior angle is equal to the sum of these two specific angles.
interior opposite
To the nearest whole number, this is the length of the hypotenuse of a right triangle with legs of 7 and 10.

1.00254 x 10^-4
If a 1/6 of a circle is shaded, how many degrees of the circle is shaded.
60
If the measure of angle 1 = 115, and angle 1 and angle 2 are alternate exterior angles, this is the measure of angle 2
115
If a triangle has interior angles of 40° and 70°, this is the measure of the exterior angle adjacent to the third interior angle.
110
Given the leg is 24 and the hypotenuse is 32, what, to the nearest whole number, is the remaining side?

1.2 x 10^4
An angle that turns through 11/18 of a circle has this degree measure.
220
To prove two lines are parallel, you could show that these specific angles—located outside the parallel lines and on the same side of the transversal—are supplementary.
