Question

Dean made a triangular wall shelf.

Answer 1

Answer:

The shelf is not a right triangle

Step-by-step explanation:

Given

$Sides = 14, 8, 8$

Required

Determine if it is a right triangle

To do this, we make use of Pythagoras theorem which implies that; the square of the longest side = the sum of the square of the two other sides.

So, we have:

$14^2 = 8^2 + 8^2$

Evaluate all squares

$196 = 64 + 64$

$196 = 128$

The above is not true because:

$196 \ne 128$

Hence, the shelf is not a right triangle
