Atriangle with angle measures of 45°, 45°, and 90° is an equilateral triangle. true false

FALSE.

Step-by-step explanation:

In an equilateral triangle, all angles are equal.

Since they add up to 180°, tke measure of each angle is

180/3 = 60°

Your triangle has two equal angles, so it is an isosceles triangle.

c. y = 1/4 x + 5

step-by-step explanation:

first, put the equation of the line on the graph into slope-intercept form

(y = mx + b):   y = -4x + 8

second, a perpendicular line has to have "an opposite/reciprocal slope" to the original slope. so, find the "m" value in your original equation (it's -4, right? )

original slope: m = -4   perpendicular slope: change the sign to its opposite and find the reciprocal ("flip" the number)

new slope is now positive (b/c the original slope was negative 4), and it's 1/4 (not the original slope of 4 or 4/1)

because parallelagram have all 4 angels the same size dependeing and a rectangle and square are oth parallelogram
