Answer : In the diagram shown above, a ° and C are linear pair. a° + C = 180°. Subtract a° from both sides. C = 180° – a°. In the triangle shown above, by Angle Sum Property of Triangle, C + 45° + 101° = 180°. Substitute C = 180 ° – a°. 180 ° – a° + 45° + 101° = 180°. ### Triangle Angle Sum Theorem Gordon State College

The angle sum property states that the interior angles of a triangle add up to 180°. Figure out if the given sets of angles form a triangle by adding them. Respond to each with ‘Yes’ or ‘No’. Finding the Interior Angle Subtract the sum of the two angles from 180° to find the measure of the indicated interior angle in each triangle. ### Triangle Angle Sum FREE Math Worksheets

the sum of the three angles of a triangle = 180 ° x + (x + 5) + (x + 10) = 180° 3x + 15 = 180° 3x = 165° x = 55° The first angle = 55 ° The second angle = 55 + 5 = 60° The third angle = 60 + 5 = 65° So, the three angles of a triangle are 55°, 60° and 65°.
