The <u>congruency theorem</u> gives you an opportunity to prove that <u>two triangles</u> are <u>congruent</u>.
Consider triangles WUT and VTU. In these triangles:
- WU≅VT (given);
- ∠T≅∠U, m∠T=m∠U=90° (from the diagram);
- side TU is common.
Note that triangles WUT and VTU are right triangles, because m∠T=m∠U=90°. Side TU is common leg and sides WU and VT are hypotenuses.
HL theorem states: if the hypotenuse (WU) and one leg (TU) of a right triangle (ΔWUT) are congruent to the hypotenuse (VT) and one leg (TU) of another right triangle (ΔVTU), then the triangles are congruent.
Answer: correct choice is B
Answer:
39
Step-by-step explanation:
180 - 141 = 39
A straight angle equals to 180, since the lines are congruent, the angles have the same measurements.
Answer:
<em><u>10 cm</u></em>
Explanation:
Surface area of cube = 600 cm^2
Side of a cube = ?
Formula:
Total S.A of cube = 6 x (side of cube)^2
= 6 . x^2
600 cm2 = 6 . x^2
x^2 = 600 / 6
x^2 = 100
x = 10 cm
<em>The required side of a cube = 10 cm</em>
that would be the circumference of the circle
= 2 pi r
= 2 * pi * 2
= 6.28 feet to 2 DP's.
