Look at the figure below: Triangle CDE has measure of angle CDE equal to 90 degrees. A is a point on the hypotenuse EC such that the segment DA is perpendicular to EC. B is a point outside the triangle on the right of C so that triangle ABC has the measure of angle ABC equal to 90 degrees. Which triangle is similar to triangle EAD?

The Answer for this is triangle DAC

Step-by-step explanation:

If you look at triangle DAC it shows the same shape also if you reflect the triangle EAD across the y-axis it flips onto triangle DAC

for finding the midpoint of any given 2 pair of points simply add the respective x coordinates with other x coordinate and the y coordinate with other y coordinate and divide them by 2

in your question it will be :

(3+1)/2 for the x coordinate of mid point i.e 2

[8+(-4)]/2 for the y coordinate of midpoint i.e 2

so coordinates of mid point of points (3,8) and (1,-4) will be (2,2)

the 4th choice is the correct one
