the angle in a rectangle is 90 degress angles in a equilateral triangle is 60 degree each. in this question they usually give you the triangle at an angle and give you what the angle is. so if you add them together they should all add to 90 degrees. so basically the trick is in what type of triangle it is.
Yes because it has three equal sides.
