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...
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. ...
The center of thne incircle of a triangle is the point where the there angle bisectors meet(the incenter).Construct the angle bisectors of A and B .They intersect at the incenter(I).The incircle is also tangent to all sides of triangle so construct the perpendicular from the incenter ...
understand that two sides of a triangle and an acute angle, not included between the two sides, may not determine a unique triangle, Common Core Grade 7
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...

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?
在一个三角形中，已知一个角和两条边，解释其不确定性。解：（1）当该角为已知边所夹时，三角形唯一；（2） 当不是已知边所夹时 (i) 若已知角大于等于90度，三角形唯一，(ii) 若已知角为锐角时三角形不唯一（有两种情况）。两
Altitude, Mean and Angle Bisector of Triangles A triangle is a geometric figure that has three straight sides connecting to create three angles. When dealing with triangles, there are many different lines that can be added inside of them to create different theorems and have different ...
