That would be a right triangle. Any triangle that has a right angle in it is a right triangle.
There could be almost any acute angle. it maters what kind it is
Your question contains the answer. It is a 'right' triangle.
With any type of triangle, the angles add up to 180 degrees. It does not matter if it is equilateral, scalene, or acute, or even right, obtuse, or acute.
Right angle. An acute angle is less than 90°. An obtuse angle is more than 90°. If it isn't less than or greater than, it must be equal to. Of course a straight angle is more or less an extreme case of an obtuse angle.
A "right" triangle, so called because it contains a "right angle".
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-angled triangle.
A right angle has a 90-degree and in two acute angles.
An obtuse triangle
60 degrees: acute
An obtuse angle
A right triangle is a triangle with a right angle.a right triangle is a triangle with 1 side as a right angle
A right triangle has a right angle (thus called a right triangle), 90 degrees
There could be almost any acute angle. it maters what kind it is
right angle triangle
A right-angle triangle.
Right angle (90) Acute angle (<90) Obtuse angle (>90) Straight angle (180) Reflex angle (>180)
