Keeping this in view, how many angles does a right angled triangle have?

The right triangle has one 90 degree angle and two acute (< 90 degree) angles. Since the sum of the angles of a triangle is always 180 degrees The two sides of the triangle that are by the right angle are called the legs and the side opposite of the right angle is called the hypotenuse.

Also Know, what are the 3 angles of a right triangle? Right triangles are triangles in which one of the interior angles is 90 degrees, a right angle. Since the three interior angles of a triangle add up to 180 degrees, in a right triangle, since one angle is always 90 degrees, the other two must always add up to 90 degrees (they are complementary).

Subsequently, question is, can a right angled triangle have 3 equal sides?

A right angle triangle can have only two equal sides. It is never possible to have all the 3 sides equal. According to Pythagorean Theorem - “In any right angled triangle the square of the hypotenuse ( the side opposite to the right angle) is always equal to the sum of squares of the sides that meet at the right angle.

How many lines of symmetry does a right angled triangle have?

A right angled triangle, if it is isosceles right angled triangle then it will have one line of symmetry. if it is equilateral right angled triangle then it will have three lines of symmetry. if it is scalene right angled triangle then it will have no line of symmetry.
