Which is a true statement about a exterior angle of a triangle?
180 degrees minus interior angle = exterior angle and that the 3 exterior angles of a triangle add up to 360 degrees.
What is an exterior angle of a triangle and how does the measure of an exterior angle relate to the interior angles?
Exterior angle+interior angle=180 degrees and 180-exterior angle=interior angle
All angles in a triangle equal 60 degrees?
If all angles in a triangle are equal to 60 degrees, then the triangle is an equilateral triangle. In an equilateral triangle, all three sides are equal in length. This property is a consequence of the triangle angle sum theorem, which states that the sum of the interior angles of a triangle is always 180 degrees. Therefore, if each angle is 60 degrees, the total sum of the angles in the triangle is 180 degrees, satisfying the theorem.
Is a triangle with a 120 degrees angle obtuse triangle?
Yes providing its 3 interior angles add up to 180 degrees
What are the angle measures of triangle ABC?
The 3 interior angles of any triangle add up to 180 degrees
The sum of the interior angles of a triangle is?
The sum of the interior angles of a triangle is 180 degrees. This is because one angle of a triangle is 60 degrees.
Does exterior angle of a triangle equals the sum of the interior angles?
Actually, no. The sum of the exterior angles of a triangle is 360 degrees. The sum of the interior angles of a triangle is 180 degrees.
The measure of an exterior angle of a triangle is120 degrees the interior angles that are not adjacent to this exterior angle are congruent find the measure of the interior angles of the triangle?
They are all 60 degrees.
What is an interior angle of a triangle?
The 3 interior angles of a triangle add up to 180 degrees
Is it possible that a triangle can have all its angles as 90 degrees?
No because the 3 interior angles of a triangle must add up to 180 degrees and only a right angle triangle has 1 interior angle of 90 degrees.
What is the measure of the interior angle of an equilateral triangle?
Each of the interior angles of an equilateral triangle is 120 degrees.
What is the interior angle measures for a triangle?
The sum of the interior angles of a triangle on a plane is always 180 degrees.
What is the interior angle of any triangle?
The 3 interior angles of any triangle add up to 180 degrees
What angles do a scalene triangle have?
-- A scalene triangle has three interior angles and three exterior angles. -- The sum of the interior angles is 180 degrees, and no two of them are equal. -- The sum of the exterior angles is also 180 degrees, and no two of them are equal. -- The sum of each interior angle and its adjacent exterior angle is 180 degrees.
What triangle has one 60 degree angle?
An equilateral triangle has 3 interior 60 degree angles but a right angle triangle can have 3 interior angles of 90, 60 and 30 degrees
What is the area of a triangle if angle a equals 42 degrees angle b equals 87 degrees and angle c equals 24 degrees?
A triangle with interior angles of 42, 87 and 24 degrees doesn't exist because the angles add up to 153 degrees whereas the interior angles of any triangle always add up to 180 degrees.
Which is a true statement about a exterior angle of a triangle?
180 degrees minus interior angle = exterior angle and that the 3 exterior angles of a triangle add up to 360 degrees.
