Determine whether you can construct many, one, or no triangle(s) with each description.

Question

1. A scalene triangle with an angle of 143° and a side length of 4 cm

One Triangle

Many Triangles

No Triangles

2. A right triangle with side lengths of 3 cm, 4 cm, and 5 cm

Many Triangles

No Triangles

3. An isosceles triangle with an angle of 170°

One Triangle

Many Triangles

No Triangles

Answer 1

1) scalene means the sides are of unequal length. there's endless possible triangles with 143 degrees and one side = 4 cm

2) just one right triangle with sides 3, 4 and 5 cm

3) 170 means the other two angles are each 5 degrees, so they sum to 180. but the sides could be all small or large, or any size, many possible triangles, all similar though in shape.
