a geometric figure; an angular projection; a projecting corner:the angles of a building;a viewpoint; standpoint:He looked at the situation from every angle. Not to be confused with: angel– a heavenly creature:Your mother is such an angel. ...
An included angle is the angle that is formed at the vertex of two adjacent legs (sides) of a triangle. Legs are adjacent if they connect at the vertex. The measurement of this angle can be used to calculate other properties and values of the triangle. This triangle has one included angl...
How to find the angle of a triangle There are several ways to find the angles in a triangle, depending on what is given: Given three triangle sides Use the formulas transformed from the law of cosines: cos(α)=b2+c2−a22bccos(α)=2bcb2+c2−a2 So: α=arccos(b2+c2−a22bc...
An interior angle of a triangle is formed by two sides of the triangle. An exterior angle is formed by one side of the triangle and the extension of an adjacent side. Each exterior angle has two remote interior angles. A remote interior angle is an interior angle that is not adjacent to...
interior angle- the angle inside two adjacent sides of a polygon internal angle angle- the space between two lines or planes that intersect; the inclination of one line to another; measured in degrees or radians reentering angle,reentrant angle- an interior angle of a polygon that is greater ...

Angle from Any Two Sides We can find anunknown anglein aright-angled triangle, as long as we know the lengths oftwo of its sides. Example The ladder leans against a wall as shown. What is theanglebetween the ladder and the wall?
of the definition of an angle bisector:#An angle bisector is the ray passing through a vertex so that it divides the angle into two equal parts.#An important property follows directly from the definition:#A point lies on an angle bisector if and only if it is equidistant from its sides鈥...
Important Formula: Sin(q) = Opposite / Hypotenuse Cos(q) = Adjacent / Hypotenuse Tan(q) = Opposite / Adjacent Select what (angle / sides) you want to calculate, then enter the values in the respective rows and click calculate. If you want to calculate hypotenuse enter the values for oth...
