Answer : 1. "TRUE"
Explanation :
Answer: A) TRUE Explanation: Yes, a square is a rhombus. But a rhombus is not a square unless the interior angles are at right angles. We know that, a square is a quadrilateral with all sides equal and all the interior angles are 90 deg i.e, at right angles. Whereas a rhombus is also a quadrilateral with all sides equal but the interior angles are not at right angles. Hence, if the interior angles of a rhombus are all at right angles (90 deg), then it is square.

Answer : 3. "away from electrical wiring"
Explanation :
Answer: C) away from electrical wiring Explanation: A compass, which is used to assist in navigation, is an instrument that shows magnetic north. You must apply a correction to determine the direction of true north. The ability to steer a boat by a compass is useful if land is out of sight, visibility is reduced, or the boat operator is disoriented. Mount a boat compass away from iron, magnets, and electrical wiring and equipment.

Answer : 3. "is described generally, not using a formal definition"
Explanation :
Answer: C) is described generally, not using a formal definition Explanation: In geometry, we can define plane as a flat surface with no thickness. The surface extends with no ends. A plane does not have any edges even if we draw it on paper with edges, it does't mean it has edges. Hence, A plane is an undefined term because it is described generally, not using a formal definition.
