Finding A Missing Angle In An Isosceles Triangle Key Stage 2

Finding A Missing Angle In An Isosceles Triangle Key Stage 2 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°. To find the missing angle: label each angle in the triangle with a letter. the unknown letter will be to the left of the =. in the image above, a is the unknown angle. choose the equation with a to the left of the =. a = 180° − b − c. insert the values of the known letters into the right hand side of the equation.

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.
