Zero triangles.. we cant draw triangle with these angles. but the given angles are 45,64.72. if we add those we get 45+64+72=181. so we cannot draw triangle.

The sum of all three angles in any triangle anouamo to 180°. If we add the given angles, i.e., 45°+64°+72°,gives us 181°. So, no triangle exists with the given angles.

Zero triangles. because we cant draw triangle with these angles. As the given angles are 45,64,72. if we add then we get, 45+64+72=181.so we can't draw triangle.

no traingle can be drawn with this measurements because the total sum of traingle =180 so its exceeds the angle
Comments

Tutor

Only one distinct triangle can be formed.We can make infinite numbers of triangle by scaling up or down its length.
Comments

Teacher

No triangles can be drawn with the three angles mentioned because the sum of all angles in a triangle must be 180, which in this case is not.
