Question

Zahra plans to draw a triangle with angles measuring 50, 60, and 70. Which is true about Zahra’s plan?

A. Zahra cannot make a triangle with these angle measures.
B. Zahra can only draw one unique triangle with these angle measures.
C. Zahra can make exacty two triangles with these angle measures.
D. Zahra can make more than one triangle with these angle measures.

Answer 1

D. Zahra can make more than one triangle with these angle measures.
(Infinite similar triangles)

Answer 2

OPtion A Zahra cannot make a triangle with these angle measures.

Explanation:

To draw a triangle we must have atleast 3 independent dimensions

Here only 2 are given as third angle depends on first 2.

Hence Zahra cannot make a triangle with these angle measures.

If at all she wants to draw she has to assume some side atleast one side and make triangle

But this is infinite as she can do for any size of her choice.
