Question

determine each of the following triangles scalene, isoceles, equilateral, cannot be determined

Answer 1

Scalene

Cannot be determined

Isosceles

Step-by-step explanation

1) This triangle is shown to have three sides of three different lengths. This means that it is a scalene triangle since a scalene triangle is one with sides of three different lengths

2) This triangle has no markings on its sides or on its angles. This means that we cannot determine the type of triangle that it is.

3) The two bottom angles of this triangle are shown to be equal. This implies that the two sides adjacent to the angles shown are also equal in length.

Hence, the triangle is an isosceles triangle since an isosceles triangle is one that has two sides and two sets of angles to be equal.
