Question

Triangle PTG has side lengths of 18cm, 14cm, and 16cm. What type of triangle is this?
A. obtuse
B. isosceles
C. acute
D. right
@bibby

Answer 1

not isosceles cause we need 2 sides to be equal for that
now we check to see how the sum of the squares of the legs compares to the hypotenuse squared
if
\(a^2+b^2=c^2 \) we have a right triangle
if
\(a^2+b^2>c^2 \) we have an acute triangle
if
\(a^2+b^2<c^2 \) we have an obtuse triangle

Answer 2

Answer 3

Is it right triangle???

Answer 4

the hypotenuse, c, is the longest side

what is the measurement of the hypotenuse and what is the measurement of the 2 legs?

Answer 5

Hypotenuse is 18, legs are 14 and 16
