What is the third measurement? Question 2: James says that a triangle is right angled. Olivia says that the same triangle is isosceles. They are both correct. Explain how. Question 3: The ratio of three angles in a triangle are 1:2:3. Work out the size of each angle. Question 4: An isosceles triangle has one angle of 52°.

Another common problem involves finding the two base angles for an isosceles triangle given the triangles vertex or apex angle. Because the legs of an isosceles triangle are equal, the corresponding adjacent angles at the triangles base are also equal, so calculating the measure of the leg angles involves substracting the vertex angle from 180° and dividing the result among …
