A ratio says how much of one thing there is compared to another thing.

The cosine of an angle is always the ratio of the (adjacent side/ hypotenuse).


mid segment in a triangle and how to compare it to a median

Same-Side Interior Angles

Created where a transversal crosses two (usually parallel) lines. Each pair of interior angles are inside the parallel lines, and on the same side of the transversal.

Real Example

Median of a triangle

median of a triangle is a line from a vertex of the triangle to the midpoint of the side

Right Triangle

triangle where one of its interior angles is a right angle (90 degrees).
Real Example

Corresponding Angles

two nonadjacent angles made by the crossing of two lines by athird lineone angle being interior, the other exterior, and bothbeing on the same side of the third line
