Question

determine the length of the longest side and the measure of the largest angle in the triangle shown below. you must use the ruler and protractor for precise measurements. the side length should be precise to the nearest tenth and the angle should be precise to the nearest degree.

Explanation:

Step1: Measure sides with ruler

Use a ruler to measure the lengths of sides \( AB \), \( BC \), and \( AC \). Let's assume (after measurement) \( AB = 3.5 \) cm, \( BC = 4.0 \) cm, \( AC = 3.8 \) cm. So the longest side is \( BC = 4.0 \) cm (or adjust based on actual measurement).

Step2: Measure angles with protractor

Use a protractor to measure the angles opposite each side. The largest angle is opposite the longest side. For side \( BC \), the opposite angle is \( \angle A \). Measure \( \angle A \) to be (e.g., after measurement) \( 80^\circ \) (adjust based on actual measurement).

(Note: Actual measurements depend on the drawn triangle. The above are example values. When measuring, place the ruler along each side to get length, and protractor with center at the vertex to measure angle.)

Answer:

Longest side length (example): \( 4.0 \) cm, Largest angle measure (example): \( 80^\circ \) (Replace with actual measurements from the triangle using ruler and protractor.)
