Ingrid wants to prove that the diagonals of a parallelogram bisect each other, using the figure below.

which statement and reason should be part of her proof?

a

△qmr≅△smt by asa

b

△qmr≅△tms by asa

c

△qrs≅△sqt by sss

d

△qrs≅△rtq by sss

A. ΔQMR ≅ ΔSMT by ASA

Step-by-step explanation:

There are two types of angle, alternating and corresponding angles.

Both compare two equal angles, but unlike corresponding angles, alternating angles faces opposite direction.

∠Q = ∠S and  ∠R = ∠T  and are both alternating angles.

intensity of the vector is v= √37 ≈ 6.08 units and make angle ∡α ≈ 9.46° with east direction

step-by-step explanation:

required vector is consists of the two componentsvx= 2+4=6 units   and vy= 1 unit and vx ⊥ vywe will use pythagorian theorem to find intensity of the vector vv∧2 = vx∧2 + vy∧2 => v = √vx∧2 + vy∧2 = √6∧2 + 1∧2 = √36+1 = √37 ≈ 6.08 unitsthe angle ∡α between vector and east direction we wil find with tanαtanα = 1/6 => α = arc tanα = arc 1/6 => α ≈ 9.46°

hope this
