All triangles have 3 sides and 3 interior angles that add up to 180 degrees and they are classified as follows:-
Scalene has 3 different acute angles
Right angle has a 90 degree angle and 2 different acute angles
Obtuse has an obtuse angle and 2 different acute angles
Isosceles has 2 equal angles and an apex angle
Equilateral has 3 equal angles of 60 degrees

Every triangle has three sides and three angles. In a right triangle, the side that is not part of the right angle is called the hypotenuse.
a perpendicular line.
hi felicia
Someone correct me if I am wrong, but I don't believe triangles can be "equal", only congruent. The measurements can be equal, but not the triangle itself.The triangle congruency postulates and theorems are:Side/Side/Side Postulate - If all three sides of a triangle are congruent to the corresponding parts of another triangle, then the triangles are congruent.Angle/Side/Angle Postulate - If two angles and a side included within those angles of a triangle are congruent to the corresponding parts of another triangle, then the triangles are congruent.Side/Angle/Side Postulate - If two sides and an angle included within those sides of a triangle are congruent to the corresponding parts of another triangle, then the triangles are congruent.Angle/Angle/Side Theorem - If two angles and an unincluded side of a triangle are congruent to the corresponding parts of another triangle, then the triangles are congruent.Hypotenuse/Leg Theorem - (right triangles only) If the hypotenuse and a leg of a right triangle are congruent to the corresponding parts of another triangle, then the triangles are congruent.
You can't. With one leg measure, all you know about the triangle is one side (the leg) and one angle (the right angle). That's not enough to pin down any of the other parts of that triangle. There are an infinite number of different right triangles that all have one leg with that same length, and hypotenuses with all different lengths.
