In the figure, 1 is an exterior angle. equiangular triangle!=equiangular triangle:ÖA triangle with three congruent angles.  equilateral triangleś!aequilateral triangle:ÖA triangle having all three sides congruent and all three angles congruent.   flow proofţflow proof:ÖA proof that organizes statements in logical order, starting with the given statements. Each statement is written in a box with the reason verifying the statement written below the box. Arrows are used to indicate the order of the statements.  included angle‡ !‚included angle:ÖAn angle formed by two given sides of a triangle. In the figure, A is the included angle of seg. AB and seg. AC .   included side‡ !yincluded side:ÖA side common to two given angles of a triangle. In the figure, seg. AB is the included side of A and B.  isosceles trianglep!Aisosceles triangle:ÖA triangle with at least two congruent sides. obtuse triangleÍ!4obtuse triangle:ÖA triangle having one obtuse angle. remote interior angles!ťremote interior angles:ÖThe angles in a triangle that are not adjacent to a given exterior angle of the triangle.
