Use the diagram as a guide. P Which reasons can Travis use to prove the two triangles are congruent? Check all that apply. - ∠ZWY ≅ ∠XYW by the alternate interior ∠s theorem. - WY ≅ WY by the reflexive property. - ∠ZWY ≅ ∠XWY by the corresponding ∠s theorem.

degree of cost uncertainty and the relative slopes of the marginal benefit and marginal cost functions. Figure 2 illustrates the corollary finding that when the uncertainty is Use the figure for Problems 5—6. SV, TV, and UV are perpendicular bisectors of the sides of APQR. Find each length.

Prove: WX = YX. (3) m∠VXW = m∠ZXY. (4). VWX∼= ZYX. (5).

The vertices of are A (-1, 5), B (5, 3) and C (1, 1). Prove that is an isosceles right triangle. Isosceles Triangle -using distance formula, prove that only two sides are congruent Right Triangle -using slope formula, prove … Two or more triangles that have the same size and shape are called congruent triangles..

### Notice that Yr is less than R at 17.5 ft, that is because the focus is not directly over the toe of the slope, but the circle intersects the toe of slope. Ym = Yr - Yt = 17.29 - 1.84 = 15.45 ft Now the angle of the passive force can be resolved.

The law of sines is useful for computing the lengths of the unknown sides in a triangle if two angles and one side are known. View 9 . 1 Properties of Parallelograms.pdf from MATH GEOMETRY at MAST@FIU. 2. AB = ½ WX. 3. XY = ½ GH 4.

Point Y is in between Points X and Z. Angles 1 and 2 are and the top of the triangle and 3 and 4 are at the bottom (Angle 1 is ANGLE WXY and Angle 2 is WYZ.) (Angle 3 is ANGLE WYX, and Angle 4 is ANGLE WYZ.
I want to find the slopes of an equilateral triangle, when given only the two vertices. Let's say they are $(0,0)$ and $(5,5)$. Graphing this would give two triangles forming a diamond.

8 Describe how each triangle relates to the slope Use the slope formula to find the slope of the sides of the quadrilateral. The slopes of each pair of opposite sides are equal. So, the two pairs of opposite sides are parallel. Therefore, the quadrilateral WXYZ is a parallelogram.

Sides "a" and "b" are the perpendicular sides and side "c" is the hypothenuse.

### 8.4 Triangle Congruence: CPCTC CPCTC is an abbreviation for the phrase “Corresponding Parts of Congruent Triangles are Congruent.” It can be used as a justification in a proof after you have proven two triangles congruent.

We are going to focus on two specific cases. Case I. When we know 2 sides of the right triangle, use the Pythagorean theorem. Case II. We know 1 side and 1 angle of the right triangle, in which case, use sohcahtoa.
