Question

Provide the ordered pairs for two similar triangles on the coordinate plane. Explain, using complete sentences, how you know these triangles are similar.

Answer 1

@abb0t help me please

Answer 2

If you have two triangles that have 2 congruent angles, then the third angles must be congruent because the angles of a triangle always sum to 180. If you have three congruent angles, then the sides must be related with a common constant of proportionality and therefore are at least SIMILAR (congruent if the constant of proportionality is 1)

Answer 3

ok but wat about similiar triangles isnt it different when it come to that and congruent triangles

Answer 4

@alrightatmaths

Answer 5

In similar triangles, all you need is for all 3 angles to be the same.

Answer 6

but isnt that for congruent triangles

Answer 7

for congruent triangles, you need all 3 angles and 3 sides to be the same.
for similar triangles, you only need all 3 angles equal, or all sides ratio equal.

Answer 8

o so can you help me do the problem

Answer 9

yes i guess

Answer 10

ok thank you

Answer 11

@nphuongsun93 r u there

Answer 12

oh this is your problem? i thought you will post another one, my bad.

as abb0t say, if you can measure the angles of the triangles and compare them, if they are equal, they are similar angles.
or if you can calculate the distance of each sides, you can calculate the ratio of corresponding sies, and if the ratio is the same, the triangles are similar

Answer 13

so help me step by step

Answer 14

please

Answer 15

for example, if you can measure 2 or more angles of triangles ABC and DEF, and they are equal. (angle A = angle D, angle B = angle E, etc.) then they are similar.

if you can measure the length of sides of the triangles, check the ratio of the sides of the triangles to see if they are equal.
(AB / DE = BC / EF, or BC / CA = EF / FD, etc.) then they are similar
