Finding Missing Angles In An Isosceles Triangle Worksheet The missing angle a is between the two sides of the same length. it is a vertex angle. the other two angles are base angles and are equal to each other. 2. the angles add up to 180°. a 70° 70° = 180°. 3. find a by subtracting the known angles from 180°. a = 180° − 70° − 70° = 40°. You know that one of the angles is 90°, represented by the right angle symbol, and another is 35°. and you also know that angles on a straight line add up to 180°. to find the unknown angle. To find angle ‘b’, we subtract both 50° angles from 180°. we first add the two 50° angles together. 50° 50° = 100°. and 180° – 100° = 80°. angle ‘b’ is 80° because all angles in a triangle add up to 180°. here is another example of finding the missing angles in isosceles triangles when one angle is known. Ab is a straight line through o. calculate the size of all the angles that make up the line ab. add all known angles. show step. form and solve the equation. show step. angles on a straight line add up to 180° so we have the equation 6x 90=180. as x = 15, substitute this into each angle to find their values:.
