A vertex angle refers to the angle that is formed by the two lines crossing at a vertex. When asked for a vertex angle, the intended query is typically for the size of the angle in degrees or radians.
A vertex is the result of two non-perpendicular lines intersecting, often forming a corner of a shape. For example, a square has four vertices due to having four sides and four corners. The angle of a vertex is measured on the inside of the shape. For a square, the angle would be measured between two connected sides, which would always be 90 degrees.

Full Answer >Geometry is essential for applied mathematics, and it is used in architecture and engineering fields. Its development was crucial in the development of modern mathematics. It can also make abstract mathematical concepts more clear.
Full Answer >Geometry is used in everyday life for building and construction, home decorating, outdoor projects and professional work. The geometric formulas for area and perimeter are often used to accomplish projects that require room and object measurements. For squares and rectangles, the area = base x height and the perimeter = base x 2 + height x 2.
Full Answer >Perpendicular lines are lines that intersect one another at a 90 degree angle. If two lines are perpendicular, then multiplying the slopes of the two lines together equals -1.
