Definition of a triangleClick to go to the multiple choice question!Click on the pictures to learn about the different types of triangles!Definition of an AngleEquiangular TrianglesAll sides are equalAll angles are equal to 60All angles add up to 180
Isosceles Triangles There are two equal sides and one unequal sideThe bottom left and right angles are equalThe top angle is acute
IncorrectA ray are two lines creating a vertex
EndpointClick to go back to the question!Right TrianglesHas a 90 angleThe longest side, which is opposite of the right triangle is called the hypotenuseThe two short sides are legs.There is one 90 angle and the other angles add up to 90
hypotenuse
