MAP, they read them and help make more accurate
A ray is a part of a line that has one endpoint but the other end continuous in the other direction infinitely. So one pair would be: RAY - <span>the portion of a line that starts at one point and goes off in a particular direction to infinity.
A point is just a location in a line or plane. It has not value and is not measured. This means that there are no dimensions considered in a point. So another pair would be: POINT - </span><span> a location, has no size
An angle is 2 rays or lines that share a common endpoint called the vertex. The symbol of an angle is </span>∠. So another pair would be: ANGLE - <span>a figure consisting of two rays with the same endpoint.
Like mentioned above, a vertex is the endpoint where two figures meet. In an angle, the vertex is the point where the two rays or figures meet. So for this pair it would be: VERTEX - </span>a point where two or more rays or "arms" of an angle meet
This would then leave CIRCLE - <span>the set of all points in a plane that are a given distance from a point. To be more specific, a circle is made when all points in the same plane lie at a distance that is equal to the CENTER point. </span>
Answer: A portable engine
Explanation:
Over the past million years, Earth's globally averaged surface temperature has risen and fallen by about 5˚C in ice-age cycles, roughly every 100,000 years or so (Figure 2.1a).
