Right triangles are aloof. Leg Acute (LA) and Leg Leg (LL) Theorems. All the parts of one figure are congruent to the corresponding parts of the other figure. Hypotenuse – Leg Postulate (HL): If a hypotenuse and a leg of one right triangle are congruent to a hypotenuse and a leg of another right triangle, then the triangles are congruent Right Angle Theorem (R.A.T. In a previous course you investigated congruent tliangles. Theorem 4.6 Angle­Angle­Side (AAS) Congruence Theorem: If the hypotenuse and a leg of a right triangle are congruent to the hypotenuse and a corresponding leg of another right triangle, then the two triangles are congruent. Hypotenuse-Leg Congruence Theorem. Problem 23 Hard Difficulty. Given AE — ⊥ EB —, AE — ⊥ EC —, AE — LA Congruence Theorem If a leg and an acute angle of one right triangle are congruent to a leg and an acute angle of another right triangle, the triangles are congruent.

HL Congruence Theorem Using the Hypotenuse-Leg Congruence Theorem The television antenna is perpendicular to the plane containing points B, C, D, and E. Each of the cables running from the top of the antenna to B, C, and D has the same length. Angie TABC cT CDA by the Hypotenuse-Leg Congruence Theorem. midsegment of a triangle. Postulate 21 Angle­Side­Angle (ASA) Congruence Postulate: If two angles and the included side of one triangle are congruent to two angles and the included side of a second triangle, then the two triangles are congruent. Corollary to Theorem 4.9: If a triangle is equiangular, then it is also equilateral. Theorem 4.10 Hypotenuse- Leg (HL) Congruence Theorem: If the hypotenuse and a leg of a right triangle are congruent to the hypotenuse and leg of a HL Congruence Theorem (HL) – If the hypotenuse and leg of one right triangle are congruent to the hypotenuse and leg of another right triangle, then the triangles are congruent. HOMEWORK HELP Extra help with problem solving in Exs. ): Vertical angles are congruent. ADG HKN T Q S R A D G H K N Mark the appropriate sides to make each congruence statement true by the Leg-Leg Congruence Theorem. Corollary to Theorem 4.8: If a triangle is equilateral, then it is also equiangular. They stand apart from other triangles, and they get an exclusive set of congruence postulates and theorems, like the Leg Acute Theorem and the Leg Leg Theorem. If they hypotenuse and a leg of a right triangle are congruent to the hypotenuse and leg of another right triangle, then the two triangles are congruent. QTR SRT 4. 5.4 Hypotenuse-Leg (HL) Congruence Theorem Objective: To use the HL Congruence Theorem and summarize congruence postulates and theorems. Angle-Leg (AL) Congruence Theorem If an angle and a leg of a right triangle are congruent to an angle and a leg of a second right triangle, then the triangles are congruent. 25–28 is at classzone .com IStudent Help leg leg hypotenuse Examples: Tell whether the segment is a leg or a hypotenuse. 1.
