Question

Which of the points below, when plotted on the graph, would connect with the other two points to form an obtuse triangle? A. (5,8) B. (9,6) C. (7,1) D. (8,3)

Answer 1

Given the question in the image, the following are the solution steps to answer the question.

STEP 1: Define an Obtuse triangle

An obtuse triangle is a triangle with one obtuse angle and two acute angles.

STEP 2: Plot the given line on a graph and connect the given points

(5,8)

STEP 3: Plot (9,6)

STEP 4: Plot (7,1)

STEP 5: Plot (8,3)

From the triangles plotted in the above images, it can be seen that:

Point C and D gives Acute triangles while Point B gives a right-angled triangle.

Hence, the correct option that gives an obtuse triangle is the points in Option A

OPTION A
