Prove that the sum of the measures of the three angles of every triangle is 180 degrees?
Angle a plus angle b subtract from 180 equals angle c
What is relationship between exterior angles and opposite interior angles of a triangle?
The exterior angle of a triangle is equal to the sum of the two opposite interior angles. So if a triangle had points A, B and C: The exterior angle at B would equal the sum of interior angles at A and C. Similarly, the exterior angle at C would equal the sum of interior angles at A and B And the the exterior angle at A would equal the sum of interior angles at C and B.
How do you determine the third angle of a triangle if 2 angles are known?
There are 180 degrees in a triangle. So, if you subtract two angles (angles A and B) from 180 degrees, you get the third angle (angle C). So: 180 - A - B = C
Is it possible an acute triangle with angels measuring 60 62 and 58?
A triangle can have any angles, as long as (a) each individual angle is greater than zero, and (b) the sum of the angles is equal to 180 degrees. Check the two conditions on the given data.
How do you find the angles of a triangle when you are given ratios?
The sum of the angles is 180 degrees. So if the ratios are a, b and c then the angles are180*a/(a+b+c), 180*b/(a+b+c) and 180*c/(a+b+c) degrees.
What possible measures for angle a and angle b with triangle abc is a right triangle with the right angle at c?
'a' and 'b' must both be acute, complementary angles.
If angle B measures 42 degrees and angle C measures 27 degrees what is the measure of angle A?
If the angles A, B and C forms a triangle, then angle A is 111 degrees.
An isocleles triangle has one angle witch measures 66 what is the measures of the other two?
In an isosceles triangle there are two equal sides and two equal angles. In a triangle ABC, if angle A is between the sides of equal length, then angles B and C are equal.Without knowing which angle (A, B or C above) is 66o there are two possible answers:If the 66o angle is between the two sides of equal length (angle A) then the other two angles (B and C) are (180o - 66o) / 2 = 57o each.If the 66o angle is not between the sides of equal length (angle B or C), then the other two angles are 66o (the other angle of C and B) and (angle A) 180o - 66o x 2 = 48o.
Isosceles triangles equal 180 degrees?
The total sum of angles of a triangle is 180, so only one angle of a triangle can be 90 ( making it a right angled triangle).However the sum of two angles of a triangle can be equal to 90, once again making it a right angled triangle.it is possible that two angle can be equal to 180-The acute angles of a right triangle are complementary.SUPPOSE ABC IS A TRIANGLE, where C = 90, thenA+B+90 = 180,A+B = 180-90or A+B = 90,or A = 90-Bso it's possible.
Exterior angle of a triangle?
Exterior Angle Theorem Exterior angle of a triangle An exterior angle of a triangle is the angle formed by a side of the triangle and the extension of an adjacent side. In other words, it is the angle that is formed when you extend one of the sides of the triangle to create a new line, and then measure the angle between that new line and the adjacent side of the original triangle. Each triangle has three exterior angles, one at each vertex of the triangle. The measure of each exterior angle is equal to the sum of the measures of the two interior angles that are not adjacent to it. This is known as the Exterior Angle Theorem. For example, in the triangle below, the exterior angle at vertex C is equal to the sum of the measures of angles A and B So, angle ACB (the exterior angle at vertex C) is equal to the sum of angles A and B.

Prove that the sum of the measures of the three angles of every triangle is 180 degrees?
Angle a plus angle b subtract from 180 equals angle c
Is it possible to have a triangle with two acute exterior angles?
No. In any triangle on a plane surface, each exterior angle is equal to the sum of the other two interior angles. Suppose A,B and C are the interior angles and a b and c the corresponding exterior angles. Then a < 90 implies that B + C < 90 and b< 90 implies that A + C < 90 This gives B+C+A+C < 180 so that A+B+C < 180 which contradicts a property of triangles.
What are the measures of two suplementary angles if the difference in the measures of the two angles is 56?
A + B = 180 A - B = 56 So 2A = 236 which gives A = 118 degrees and then B = 180 - A = 62 degrees.
What is relationship between exterior angles and opposite interior angles of a triangle?
The exterior angle of a triangle is equal to the sum of the two opposite interior angles. So if a triangle had points A, B and C: The exterior angle at B would equal the sum of interior angles at A and C. Similarly, the exterior angle at C would equal the sum of interior angles at A and B And the the exterior angle at A would equal the sum of interior angles at C and B.
How do you determine the third angle of a triangle if 2 angles are known?
There are 180 degrees in a triangle. So, if you subtract two angles (angles A and B) from 180 degrees, you get the third angle (angle C). So: 180 - A - B = C

If a right triangle has 28 degrees angle what are the measures of the other angles a 28 and 62 b 28 and 90 c 62 and 90 or d 62 and 118 degrees?
The other 2 angles are c 62 and 90 degrees
