Graph a triangle (STU) and reflect it over the y-axis to create triangle S'T'U'. Describe the transformation using words. Draw a line segment from point S to the reflecting line, and then draw a line segment from point S' to the reflecting line. What do you notice about the two line segments you drew? Do you think you would see the same characteristic if you drew the line segment connecting T with the reflecting line and then T' with the reflecting line? How do you know?

after simplifying it i got: -36.25 as my answer. hope that !

pentagon

step-by-step explanation:

the coordinates   a(5, -2), b(3,-1),c(-4,-4) d(-3,8) and e(-1,4) forms the vertices of the polygon when they are connected in order.

in order to classify that which polygon is it with the given coordinates, first count the number of vertices and then count the number of sides it can make with these vertices.

since, the given coordinates have five vertices, therefore, it will make five sides. moreover, pentagon is regular in nature therefore it will be convex.

now, a polygon with five sides is known as pentagon, therefore, the given polygon is the pentagon.

other answer is correct. i had used the radius of the radius somehow. a website:
