If you wish to show that two triangles are similar, which statement(s) is correct? you may choose more than one correct answer.
it is enough to show that one pair of corresponding angles is congruent.
it is enough to show that two pairs of corresponding angles are congruent.
it is enough to show that two pairs of corresponding sides are in the same ratio.
it is enough to show that all three pairs of corresponding sides are in the same ratio.
it is not enough to have information about only sides or only angles.

The  statements which are correct are:

Step-by-step explanation:

If two triangles have two pairs of sides in the same ratio and the included angles are also equal, then the triangles are similar.

Two triangles are similar if they have:

There are three ways to find if two triangles are similar: AA, SAS and SSS:

1)

It is enough to show that two pairs of corresponding angles are congruent.

because if two triangles will be congruent than automatically the third will also be congruent and  hence we can apply AA similarity.

2)

It is enough to show that all three pairs of corresponding sides are in the same ratio.

Hence, it will imply SSS similarity.

Hence, these two conditions would be enough to show that the triangles are similar.

34.5 cm

step-by-step explanation:

generally for a circular segment of angle, θ° and radius r

arc length

= (θ/360) x circumference

= (θ/360) x 2πr

in our case, θ = 60°, π=3.142 and r = 33 cm

substitute into above formula

arc length

= (60/360) x 2(3.142)( 33) = 34.5 cm

answer: both chords and diameters have two endpoints on a circle. diameters must intersect the center of a circle.
