Which statements are true? (plato users)

if all angles of a quadrilateral are right angles, then the quadrilateral must be a square.

two shapes are similar if and only if their corresponding angles are equal.

all quadrilaterals have four sides, and the sum of all angles in a quadrilateral is 180°.

if the diagonals of a quadrilateral are perpendicular bisectors, then the quadrilateral must be a rhombus.

there are three vertices in a triangle, or there are four sides in a pentagon.

any two triangles are either similar or congruent.

answer: the answer to your question is parallel

7 weeks

step-by-step explanation:

convert each fraction to the least common multiple of 20, so 3/4 = 15/20 & 1/10 = 2/20, then divide 15 by 2 and you get a little over 7, so the food will last 7 weeks.

∠lno ≅ ∠lnm

∠oln ≅ ∠mln

step-by-step explanation:

given   that triangle lno is congruent to triangle lnm.

we have to fill up the blanks in the given question.

according to above order of congruency   kept in mind we can say that

∠lno ≅ ∠lnm

∠oln ≅ ∠mln

ln ≅ ln due to common in both.

hence, by sas congruency,

the side angle side rule   states that if two sides and the included angle of one triangle are congruent to another triangle, then these two triangles are congruent.
