Ext angle property
WebProve: ABC ≅ FGH. Step 1: We know that ABC ≅ FGH because all right angles are congruent. Step 2: We know that BAC ≅ GFH because corresponding angles of parallel lines are congruent. Step 3: We know that BC ≅ GH because it is given. Step 4: ABC ≅ FGH because of the. B. AAS congruence theorem. WebProperties. An exterior angle of a triangle is equal to the sum of the opposite interior angles. For more on this see Triangle external angle theorem. If the equivalent angle is taken at each vertex, the exterior angles always add to 360° In fact, this is true for any convex polygon, not just triangles. See Exterior angles of a polygon. In the ...
