What is the measure of the third angle of a triangle if one angle measures 15 degrees and the other measures 85 degrees?
The sum of the measures of the angles of a triangle is 180 degrees. First, calculate the sum of the two known angles. Then subtract that result from 180. That difference is the measure of the third unknown angle. Given: One angle of a triangle is 15 degrees and the second angle of the triangle is 85 degrees. To find: We need to find the third angle of the triangle. Let the third angle of the triangle be x. We know that the sum of the angles in a triangle is 180 degrees. ==> 15 degrees + 85 degrees + x degrees = 180 degrees. ==> 100 degrees + x degrees = 180 degress. ==> x = 180 degrees - 100 degrees. ==> x = 80 degress. Therefore the third angle of the triangle is 80 degrees.
The sum of the first two angles of a triangle are twice the measure of the third angle The first angle is half of the second angle What are the three angles?
The angles are 40, 80 and 60 degrees.
A right triangle has 32 degree angle find measures of other two angles?
90 degrees and 78 degrees since one of the angles must be 90 degrees. We have 90+32=122 which is the second angle. Now the sum of the angles is 180 so 180-122=78 which is the third angle.
What is an asa triangle?
ASA is not a triangle, it is a method of proving that two triangles are congruent. ASA refers to showing that if two angles and a side (Angle-Side-Angle) of one triangle are the same measures as the corresponding angles and side of another triangle, then the two triangles are congruent. Since the three angles sum to 180 degrees, if two of them in one triangle are equal to the corresponding angles in the second triangle, then the third set of angles must also be equal. Consequently, ASA is equivalent to AAS and SAA. That is NOT The case with two sides and an angle, where it must be the included angle that is equal.
Can an obtuse triangle have a right angle as one of its angles give reason?
No The reason is that an obtuse angle is over 90o so with a second angle of 90o you already have angles totalling more than 180o which is impossible in a triangle.

Therefore the third angle of the triangle is 80 degrees.
The sum of the first two angles of a triangle are twice the measure of the third angle The first angle is half of the second angle What are the three angles?
The angles are 40, 80 and 60 degrees.
What are 26 facts and their applications of angles from A to Z in consecutive order?
Angles and their geometrical applications from A to Z are as follows:- 1 Acute angles are greater than 0 but less than 90 degrees 2 Base angles of an isosceles triangle are equal 3 Circumference of a circle has 360 degrees 4 Degrees, minutes and seconds are measurements of angles 5 Exterior angles of polygons add up to 360 degrees 6 F as a letter has corresponding equal angles 7 Greater the angle then greater the turn or rotation 8 Hexagon has 6 angles that add up to 720 degrees 9 Isosceles triangle has 3 interior angles adding to 180 degrees 10 Joint angles of 95 and 85 degrees are supplementary or 180 degrees 11 Kite has 4 interior angles which add up to 360 degrees 12 L as a letter has a right angle which means 90 degrees 13 Minute is 1/60 of a degree 14 Nonagon has 9 inner angles that total 1260 degrees 15 Obtuse angle is greater than 90 but less than 180 degrees 16 Perpendicular lines intercept at right angles 17 Quadrilaterals have 4 inside angles with a sum of 360 degrees 18 Reflex angles are greater than 180 but less than 360 degrees 19 Second is 1/60 of a minute 20 Triangles all have 3 interior angles that add up to 180 degrees 21 Undecagon has 11 sides with inner angles of 1620 degrees 22 Vertical opposite angles are equal 23 West has a bearing of 270 degrees from north 24 X as a letter creates vertical opposite equal angles 25 Y axis forms 90 degrees with the X axis on the Cartesian plane 26 Z as a letter has equal alternate angles
If you know the degrees of two angles in a triangle but must find out the third would you add the two angles and divide by 2?
No. The three angles, together add to 180 degrees. So you should add the two angles and take their sum away from 180. Example: first angle 35 degrees, second angle 75 degrees 1. Sum of first two angles = 35 + 75 = 110 degrees. 2. 180 degrees - 110 degrees = 70 degrees. 3. Answer: third angle = 70 degrees.

A right triangle has 32 degree angle find measures of other two angles?
90 degrees and 78 degrees since one of the angles must be 90 degrees. We have 90+32=122 which is the second angle. Now the sum of the angles is 180 so 180-122=78 which is the third angle.

Two angles are supplementary and one of them is 30 degrees what is the measurement of the second house
If two angles and the included side of one triangle are congruent to two angles and the included side of a second triangle then the two triangles are congruent This is known as what?
SAS
If two angles are supplementary and one of them is 30 degrees what is the measurement of the second angle?
If two angles are supplementary, and one angle measures 30 degrees, then the second angle must measure 150 degrees. This is because by definition if two angles are supplementary, then they must up to 180 degrees.
What is the meaning of AAA Similarity Theorem?
If three angles of one triangle are congruent to three angles of another triangle then by the AAA similarity theorem, the two triangles are similar. Actually, you need only two angles of one triangle being congruent to two angle of the second triangle.
