Step-by-step explanation:
parallel lines are lines in a plane which do not meet; that is, two straight lines in a plane that do not intersect at any point are said to be parallel.
When two or more lines cross each other in a plane, they are called intersecting lines.
a polygon is a plane figure that is described by a finite number of straight line segments connected to form a closed polygonal chain or polygonal circuit.
A triangle is a polygon with three edges and three vertices. It is one of the basic shapes in geometry.
An obtuse angle is a type of angle that is always larger than 90° but less than 180°. In other words, it lies between 90° and 180°.
an isosceles triangle is a triangle that has two sides of equal length.
altitude drawn to the base of a triangle is called median, b) a median drawn to the base of a triangle is known as an altitude.
