Question

Iftriangle abcd if a=3cm,b=4cm,and c=5cm.then

Answer 1

No two sides are the same length, so we know we have a scalene triangle. But what about the angles?

The Pythagorean Theorem states that in a right triangle a^2 + b^2 = c^2.

The extended version of this theorem is that in an acute triangle, a^2 + b^2 > c^2, and in an obtuse triangle, a^2 + b^2 < c^2.

Apply this to the given triangle. a^2 + b^2 = 4^2 + 5^2 = 16 + 25 = 41. c^2 = 6^2 = 36.

41 > 36. So we have an acute triangle, too.

Answer 2

Answer:

solve the pythagoras theorem a=3, b=4, c=?
