Back

Δy/Δx

Front

What proof do you need to use to show that the two triangles below are similar?

Back

SAS~

Front

Define Slope in mathematics.

Back

The ratio of the vertical change (Δy) to the horizontal change (Δx) between two points on a line.

Front

What does AA~ stand for in triangle similarity?

Back

Angle-Angle Similarity; if two angles of one triangle are equal to two angles of another triangle, the triangles are similar.

Front

What does SAS~ stand for in triangle similarity?

Back

Side-Angle-Side Similarity; if two sides of one triangle are proportional to two sides of another triangle and the included angles are equal, the triangles are similar.

Front

What does SSS~ stand for in triangle similarity?

Back

Side-Side-Side Similarity; if the three sides of one triangle are proportional to the three sides of another triangle, the triangles are similar.

Front

What does ASA~ stand for in triangle similarity?

Back

Angle-Side-Angle Similarity; if two angles and the included side of one triangle are equal to two angles and the included side of another triangle, the triangles are similar.

Front

How do you calculate the slope of a line given two points (x1, y1) and (x2, y2)?

Back

Slope (m) = (y2 - y1) / (x2 - x1)
