Answer:
TYPES OF LINES
PERPENDICULAR LINES
1. In elementary geometry, the property of being perpendicular is the relationship between two lines which meet at a right angle. The property extends to other related geometric objects. A line is said to be perpendicular to another line if the two lines intersect at a right angle
INTERESTING LINES
2. When two or more lines cross each other in a plane, they are called intersecting lines. The intersecting lines share a common point, which exists on all the intersecting lines, and is called the point of intersection.
PARALLEL LINES
3. Parallel lines are lines in a plane that are always the same distance apart. Parallel lines never intersect. Perpendicular lines are lines that intersect at a right (90 degrees) angle.
TYPES OF ANGLES
ACUTE ANGLE
1. Acute angles measure less than 90 degrees. Right angles measure 90 degrees. Obtuse angles measure more than 90 degrees.
RIGHT ANGLE
2. In geometry and trigonometry, a right angle is an angle of exactly 90° (degrees), corresponding to a quarter turn. If a ray is placed so that its endpoint is on a line and the adjacent angles are equal, then they are right angles
OBTUSE ANGLE
3. An obtuse angle has a measurement greater than 90 degrees but less than 180 degrees. However, A reflex angle measures more than 180 degrees but less than 360 degrees.
STRAIGHT ANGLE
4. an angle whose sides lie in opposite directions from the vertex in the same straight line and which equals two right angles.
REFLEX ANGLE
5. A reflex angle is the larger angle, it's always more than 180° (half a circle) but less than 360° (A full circle).
