Which is the definition of an exterior angle of a triangle?
an angle that forms a linear pair with one of the interior angles of the triangle.
What is the measure of angle A in triangle ABC if B equals 15 degrees C equals 65 degrees and side a equals 19?
If you are really talking about a closed triangle ABC, then the length of side "a" (given as 19) does not matter in the calculation. Sum of the angles of a triangle is 180 degrees. Angle B and C add up to 15 + 65 = 80 degrees. Hence angle A is (180 - 80) = 100 degrees
What is the differences between triangle and angles?
In geometry, an angle is the figure formed by two rays sharing a common endpoint, called the vertex.A triangle is a geometric shape formed by three angles ("triangle" from the words "tri" and "angle" literally meaning "THREE ANGLES")
What is the angle when 3 triangle angles are added together?
The 3 interior angles in any triangle add up to 180 degrees.
What do all the angles in a obtuse triangle if the obtuse angle is 120 Degrees?
If triangle has one obtuse angle other two angles are acute. Since, sum of angles of triangle is 180.
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.
What is the measure of the third angle of a triangle if two angle measures 42 degrees?
96˚all angles to a triangle equals 180˚
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.
Do rhombuses have right angles?
Triangles do not necessarily have right angles, but they can. A triangle with a right angle is called a right triangle. A triangle cannot have more than one right angle, since the total of all three angles of every triangle equals 180°.
What is the measure of each exterior angle of a triangle?
Any exterior angle of a triangle always equals the sum of the two interior opposite angles.
What is the sum fo the angle measure of a triangle?
The sum of all angles in any triangle equals 180 degrees.
If angle A equals 32 and angle B equals 58 What type of triangle is it?
all the angles in a triangle have to add up to 180. to find the missing angle : 180 - 32 - 58 = 90 90 is a right angle and since there is a right angle in the triangle, it is a right angled triange
What if the sum of two angles of a triangle equals 120 degrees the third angle is 60 degrees because the sum of all angles in a triangle equals 180 degrees?
Yes the 3 interior angles of any triangle always add up to 180 degrees.
What are the different kinds of angles and triangle according to size and its angles?
Angles: acute angle, obtuse angle, right angle Triangles: isosoles triangle, scalene triangle, equadrital triangle, right triangle, acute triangle, obtuse triangle
Does a right angled triangle is one angle always a right angle?
Yes. A right triangle is a triangle where one angle is a right angle. If two out of three angles are right angles, then it's an isosceles triangle. If all three angles are right angles, then it is an equilateral triangle.
Httpwww.answers.comQIn triangle ABC angle A equals 17 and angle B equals 100 what is the measure of angle C?
Anglw C is 63 degrees because the 3 interior angles of a triangle add up to 180 degrees
How do you calculate the missing degree of a triangle?
The sum of all the angles in a triangle equals 180o. To find the missing angle, subtract the sum of the two known angles from 180o.ExampleTwo angles of a triangle are 35o and 62o. What is the third angle?Solution180o - (35o + 62o) =180o - 97o = 83o
