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.

All three angles inside an equilateral triangle are 60 degrees each.
Yes. That is why it is called a right angle triangle!Yes. That is why it is called a right angle triangle!Yes. That is why it is called a right angle triangle!Yes. That is why it is called a right angle triangle!
A right angle triangle
A right angle triangle.
ABC angle is an angle,not a triangle!
Types of triangle ; EQUILATERAL all three sides the same length and all three angles are 60 degrees. ISOSCELES Two sides the same length and two angles have the same degrees value. RIGHT-ANGLED All three sides can be of different lengths. However, it MUST have one Right-Angle (90 degrees) SCALENE All three sides of different lengths and all three angles of different angular values. NB In ALL four cases the sum of the interior angles MUST ADD TO 180 DEGREES.
