A wheel has equally spaced lug bolts. What is the measure of the central angle determined by two consecutive lug bolts if there are a) 5 bolts? b) 6 bolts? To determine

a)

To calculate:

The measure of central angle determined by two consecutive lug bolts if there are 5 bolts.

Explanation

Given:

A wheel has equally spaced 5 lug bolts.

Postulate used:

Central angle postulate:

In a circle, the degree measure of a central angle is equal to the degree measure of its intercepted arc.

Congruent arcs:

In a circle or congruent circles, congruent arcs are arcs with equal measures.

Theorem:

In a circle or congruent circles, congruent minor arcs have congruent central angles.

Calculation:

Consider five bolts that are equally spaced on a wheel.

The wheel resembles the shape of a circle.

Thus the arcs formed by five bolts on the wheel are congruent arcs.

Hence if we consider the central angles for each arc, they will be congruent because the arcs are congruent...

To determine

b)

To calculate:

The measure of central angle determined by two consecutive lug bolts if there are 6 bolts.
