WebTo be perpendicular, they only need to have opposite reciprocal slope. For example, the lines, y=3x+8 and y= - (1/3)x-3 would be perpendicular because -1/3 is the opposite … WebApr 26, 2024 · Applications of Perpendicular Bisector Theorem There are multiple uses of this theorem in our daily lives, some of which include: 1. It is extensively used in the construction of bridges. 2. It is also used for the erection of towers and installing guy-wires around it. 3. It is used in making tables of different sizes and lengths. Example 1:
WebDisproof by counterexample is when we find one or more cases that demonstrate that a conjecture is incorrect. This is different to the rest of our proofs, as this is the only one that directly disproves a statement. Finding a suitable example is the quickest way to disprove a statement. We only need one example of when the statement is false.
WebTwo sides and the included angle are congruent AC = ZX (side) ∠ ACB = ∠ XZY (angle) CB = ZY (side) Therefore, by the Side Angle Side postulate, the triangles are congruent. Included Angle The included angle means the angle between two sides. In other words it is the angle 'included between' two sides. Identify Side Angle Side Relationships pink white outWebOnly one possible answer will be shown for each question. 1. Given: m n and a b Prove: ∠ 3 ∠13 Proof 2. Proof 3.
