Yes.
a right triangle has one right angleA triangle with a right angle is a right triangle.
A right angle triangle
A triangle with 1 right angle is a right angle triangle.
No, a triangle can have up to one right angle, but it doesn't have to be a right angle in order to be a triangle. A right triangle had one right angle. so, NO
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.
A right triangle is a triangle with one of its angles being 90o. The requirements for the other two angles are that they both be acute and total to 90o. Therefore, the largest possible acute angle in a right triangle is 89.99999...o.
right-angle triangle has at least one right angle .
A right angle triangle.
A triangle can have a minimum of zero acute angles, which occurs in the case of a right triangle (which has one right angle) or an obtuse triangle (which has one obtuse angle). Therefore, it is possible for a triangle to have no acute angles at all.
A triangle that has one right angle and is isosceles is called an isosceles right triangle.
Any triangle can have a maximum of one right angle. Most right triangles are scalene triangles. The only non-scalene right triangle is a 45° - 45° - 90° isosceles right triangle. It is not possible to have an equilateral right triangle in plane geometry. A scalene triangle does not have to have a right angle, but it can have one.
A right triangle is a triangle in which one angle is a right angle (that is, a 90-degree angle). The relation between the sides and angles of a right triangle is the basis for trigonometry.
