All angles add up to equal 180 degrees. 180 divided by three angles= so each angle would equal 60.

How many angle of a triangle?
there are 3 angles in a triangle which is mathematically true if you check in the math rule book and rule determined by Andres Schavascapel
What kind of triangle has angles 50 degrees 65 degrees and 65 degess?
Isosceles Triangle. An isosceles triangle is a triangle with (at least) two equal sides/ angles.
Can a right triangle have two angles that measure of 25 and 65?
Yes. The general rule for angles is that the sum of the angles must be 180 degrees.
What is the 2 angle rule for a triangle?
If you know two of the angles of a planar triangle you automatically know the third because the three angles always add up to exactly 180°.
If the only information given about an oblique triangle is the lengths of the three sides which method should you use to solve for the angles?
By using the cosine rule in trigonometry the angles of the triangle can be worked out.
How do you find the angles of a triangle that is not a right triangle if you only have the side measurements?
If it's not a right angled triangle and you don't have any of the angles but have the values of all three sides, then you need to use something called the Cosine Rule.
Does a triangle have 3 different angles?
depends on what triangle you are talking about ========================================= The three angles in a triangle can be anything you want. Two of the three can be equal, all three can be equal, or they can all be different if that's what you want. The only rule you have to follow is: The measures of the three angles in one triangle have to add up to 180 degrees.
How and by its angles do you describe each triangle by its sides?
Equilateral triangle-All three sides are equal-All three angles measure 60 degreesIsosceles Triangle-Two equal sides-Two equal anglesScalene Triangle-Three unequal sides-No rule for angles (just have to add up to 180 degrees)
If two angles in a triangle are congruent to two angles in another triangle then the angles are also congruent.?
If two angles in a triangle are congruent to two angles in another triangle, then the ______________ angles are also congruent.
Does a scalene triangle have congruent angles?
No, An equilateral triangle has 3 congruent angles, an isosceles triangle has 2 congruent angles, a scalene triangle has no congruent angles.
What if two angles of a triangle are complemenatr what is the measure of the third angle?
The sum of two complementary angles is 90 degrees. The three angles of a triangle add up to 180 degrees. Hence, if you subtract the complementary angles from 180, you have the measure of the third angle: 180 - 90 = 90 (this is the third angle) As a rule, if two angles of a triangle are complementary, the third angle is a right angle (90 deg). The three angles together form a right triangle.
How do you calculate angles in a scalene triangle?
If you know the lengths of the sides, you can use the cosine rule. If you have information about other aspects of the triangle, then other formulae will apply.
