There are 3 interior angles in a triangle that add up to 180 degrees and the 3 consecutive angles of 59, 60 and 61 degrees inside a scalene triangle add up to 180 degrees.
A triangle with 1 right angle is a right angle triangle.
An obtuse triangle has an obtuse angle.
A 90o angle is a right angle, and a triangle with a right angle is called a right triangle.
A 90o angle is also called a Right Angle, so a triangle that has one 90o angle is a Right angle triangle.
Yes. The bisector of one angle of a triangle is the perpendicular bisector of theopposite side if the bisected angle is the vertex angle of an isosceles triangle,or any angle of an equilateral triangle.
An isosceles triangle perhaps?
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.
A triangle with 1 right angle is a right angle triangle.
An interior angle is any angle on the interior of the triangle.
It could be a right triangle if it has a right angle (90 degrees). If it does not have a right angle, then it is an acute triangle.
1. A triangle is a right triangle if and only if it has a right angle. 2. A triangle has a right angle if and only if it is a right triangle.
-- No right triangle, acute triangle, or equilateral triangle has an obtuse angle in it. -- If a triangle has an obtuse angle in it, then it's called an obtuse triangle. -- No triangle can have more than one obtuse angle in it .
A right angle triangle has a right angle and two acute angles that all add up to 180 degrees.
