Obtuse triangle
A triangle with the third angle that measures 30 degrees.This triangle is not isosceles nor equilateral but has one obtuse angle.
A right angle triangle has 2 acute angles that add up to 90 degrees, along with 1 right angle of 90 degrees.
A Right Triangle or sometimes called a Right-angled Triangle has one angle = 90 degrees
An obtuse triangle has one angle greater than 90 degrees.
A triangle with one angle over 90 degrees is an obtuse triangle.
It has 180 degrees, but one angle of the triangle has to be 90 degrees
A Right Triangle is a triangle that has one corner with a 90-degree angle. So a Right Angle is an angle of 90 Degrees or also known as Perpendicular angle.
A right triangle is a triangle in which one angle is equal to 90 degrees and the remaing two angles are acute(ie., less than 90 degree). so this triangle is a right angle triangle.
An obtuse angled triangle.
40 degrees
Right angled triangle because the third angle must be 90 degrees.
right angle triangle
A right triangle
The right angle of a right-angle triangle, like all right angles, is 90 degrees or one quarter of 360 (a full circle). All the angles of any triangle will add up to 180 degrees.
The sum of the angles of a triangle is 180 degrees. So we have: 80 + 60 = 140 degrees, the sum of the two angles of the triangle 180 - 140 = 40 degrees, the measure of the third angle. Thus the measure of the third angle is 40 degrees.
All the angles of a triangle add up to 180º So if you have 80º and 60º then the remaining angle must be 40º.
