well the same shape of a triangle but a different size makes a triangle similar to each other, but do they have to be proportional... Im a bit confused on what proportional mean in the case of similar triangles.

assume the sides of a triangle are lengths 3, 4, and 5. this triangle will have the same angles of o triangle with side lengths of 6, 8, and 10. Triangles are amazing and are the basic shapes for geometry. essential to learning trig

Two triangles are similar if two angles of one are equal to two angles of the other. This really means that all the angles are = to all the angles of the othere because if 2 angles are = , then the 3rd angles must also be =.
Similar triangles have their corresponding sides proportional to each other. If triangle ABC similar to triangle DEF, then
AB/DE = BC/EF = AC/DF or
AB/BC = DE/EF, etc
This is frequently used so please take the time to thoroughly understand it.

The easiest way to check if two triangles are similar is to check their angles. If all three angles of a triangle are equal to the three angles of the corresponding angles of the other triangle, the two triangles are similar.

IT means the two triangles has to have to same rate of proportion
for example : if one triasngle has the propor. rate of 3 : 5 then the second triangle has to have the same rates

Yes, all sides of a triangle are proportional to their corresponding sides of the other one.

all angle sizes in the 1st triangle have a corresponding angle in the other
