How do you find endpoints?

The fastest way to find the missing endpoint is to determine the distance from the known endpoint to the midpoint and then performing the same transformation on the midpoint.  In this case, the x-coordinate moves from 4 to 2, or down by 2, so the new x-coordinate must be 2-2 = 0.

Step-by-step explanation:

The endpoints of the line segment are given by (x 1, y 1) and (x 2, y 2 ). To find the x-coordinate of the midpoint, use the formula: x = (x 1 + x 2 )/2. To find the y-coordinate, use the same formula, but this time, using the y-coordinates of the endpoints: y = (y 1 + y 2 )/2. Hope this helps.

b. an equilateral triangle inscribed in a circle

step-by-step explanation:

we are given the figure of two circles having a triangle inside.

now, we know that,

"when a figure is lying inside an another figure, then the outside figure is known as circumscribed figure and the figure lying inside is referred to as the inscribed figure".

as we see that, the circles are containing the triangle completely.

thus, the circles are the circumscribed figures and the triangle is the inscribed figure.

hence, we get, 'an equilateral triangle is inscribed in a circle'.
