When given 3 triangle sides, to determine if the triangle is acute, right or obtuse:
1) Square all 3 sides.
2) Sum the squares of the 2 shortest sides.
3) Compare this sum to the square of the 3rd side.
if sum > 3rd side² Acute Triangle
if sum = 3rd side² Right Triangle
<span>if sum < 3rd side² Obtuse Triangle

1) 144

<span>
1,225

1,369
144 + 1,225 = 1,369
Therefore, it is a right triangle.

Repeaterd use of figures of one kind or more to cover a plane without gaps and without overlaps is called tessellation.
only equilateral triangles squares and regular hexagons can form tessellation.
it is because each of their interior angles should be a factor of 360°. only these 3 kinds satisfy this.
1/5 is 0.2 that times 12 is 2.4 so 2.4 or 2 pizzas is you round it which you can't
