Question

. Find the perimeter of a triangle with vertices A(–3, 5), B(–3, 2), and C(1, 2)

Answer 1

12

Explanation:

Input interpretation: triangle | vertex coordinates (-3, 5) | (-3, 2) | (1, 2) | perimeter

Result: 12

Properties of Triangle:

• edge lengths | 3 | 4 | 5

• area | 6
• perimeter | 12
• interior angles | (cos^(-1)(4/5) rad | cos^(-1)(3/5) rad | π/2 rad)≈(0.643501 rad | 0.927295 rad | 1.5708 rad)
• interior angle sum | 180° = π rad≈3.142 rad
