Question

Sails are often found in the shape of a triangle. In the next items 1–2, classify each triangular sail by its angles. 1._____________, 2__________. *

Answer 1

Respuesta:

1. An isosceles rectangular triangle
2. A rectangular triangle

Explicación paso a paso:

Both are rectabgular triangles because both have a 90 degree angle, the other angles can be different but if a triangle has a 90 degree angle, then it's a rectangular triangle.

In the case of the first one, besides the 90 degree angle, it has 2 angles with the same proportion, which is why is isosceles, but it's still rectangular, because of the other angle.
