(1) Line. #3 (Question 7- 9). Data Sufficiency Question #9: Length of Triangle Side (1) Angle XYW is exterior to triangle WYZ and therefore is equal to the sum of angles WZY an How could you justify that AABC is a right triangle? A. The slope of BC = - and the slope of BA== What are the ways to prove two triangles are congruent? 39.

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. triangle WXY has side lengths XY = 14 and WX = 8. the tangent to the circumcircle of traingle WXY at X is drawn, and the line through W that is parallel to this tangent intersects line WY at Z. find YZ. In the smaller triangle, the length of the blue dotted line segment is three units. In the larger triangle, the length of the blue dotted line segment is six units. 7 Describe how the triangles relate to each other.

The slopes of XY and WX have opposite signs. The slopes of XY and YW have the same signs. bisected, each right triangle created by the diagonals is an isosceles right triangle. The acute angles of these triangles have measure 45°, so all the angles of the parallelogram have measure 90°.

Show that, out of the orthogonal projections of R onto WX, XY, YZ, and ZW; one out of these 4 points is the orthocenter of the Stack Exchange Network Stack Exchange network consists of 176 Q&A communities including Stack Overflow , the largest, most trusted online community for developers to learn, share their knowledge, and build their careers. where R is the triangle's circumradius. It can be proven by dividing the triangle into two right ones and using the above definition of sine. 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.

For triangle XYW, the slope of WX is , the slope of XY is 0.56, and the slope of YW is . Which statement verifies that triangle WXY is a right triangle? The slopes of WX and YW are opposite reciprocals. The slopes of WX and XY are opposite reciprocals. The slopes of XY and WX have opposite signs. The slopes of XY and YW have the same signs.

In the larger triangle, the length of the blue dotted line segment is six units. 7 Describe how the triangles relate to each other. The two triangles are similar. They have the same shape but not the same size. 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.

Write an expression for the slope of a segment given the coordinates of the endpoints. (For review, see the sum of the measures of the angles in a triangle is 180, we can easily find this sum. Make a that WX. ZY, XY. WZ, and WY. X

90° Two right triangles can be considered to be congruent, if they satisfy one of the following theorems. Theorem 1 : Hypotenuse-Leg (HL) Theorem. If the hypotenuse and one leg of a right triangle are equal to the hypotenuse and one leg of another right triangle, then the two right triangles are congruent. Step 1 Find the slope m of the perpendicular line. The line y = 2x + 8 has a slope of 2. Use the Slopes of Perpendicular Lines Theorem (Theorem 3.14). 2 ⋅ lines is m = −1 The product of the slopes of ⊥ −1.

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.
