Question

Step 1 - Identify formulas we will use to prove the properties of the polygons we’re working with and the kind of answer we expect to find.

(Multiple Choice)
(Hint: Each question, 1-3 here, will have 2 answers)

_____1.) Midpoint formula
_____2.)Slope formula
_____3.)Distance formula

Answer 1

Solution:

(1) Midpoint:

A point in the middle of the line segment that divides it into two equal parts.

Mid point formula:

$\left(\frac{x_{1}+x_{2}}{2}, \frac{y_{1}+y_{2}}{2}\right)$

Middle of a segment; in the form of a coordinate plane.

(2) Slope:

To find the slope of the line when passing through two points.

Slope formula:

$\frac{y_1-y_2}{x_1-x_2}$

(3) Distance:

To find the distance of two points.

Distance formula:

$\sqrt{(x_1-x_2)^2+(y_1-y_2)^2}$
