What is the Midpoint Formula?

Back

The Midpoint Formula is used to find the midpoint (M) of a line segment with endpoints (x1, y1) and (x2, y2). It is given by: M = ((x1 + x2)/2, (y1 + y2)/2).

Front

Find the midpoint of the segment with endpoints (4, 12) and (-6, 14).

Back

(-1, 13)

Front

Find the midpoint between (3, -1) and (8, -6).

Back

(5.5, -3.5)

Front

What is the definition of slope in geometry?

Back

Slope is a measure of the steepness of a line, calculated as the ratio of the vertical change (rise) to the horizontal change (run) between two points on the line.

Front

Find the slope of the line that passes through (2, 4) and (6, 12).

What is an Isosceles Triangle?

Back

An Isosceles Triangle is a triangle that has at least two sides of equal length.

Front

What type of triangle has all sides of different lengths?

Back

Scalene Triangle.

Front

What is the formula to calculate the slope between two points (x1, y1) and (x2, y2)?

Back

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

Front

Find the other endpoint of the line segment with the given endpoint (4,0) and midpoint (-2,8).

Back

(-8, 16)

What is a Right Triangle?

Back

A Right Triangle is a triangle that has one angle measuring 90 degrees.
