What composition of transformations will create a pair of similar not congruent triangles?
Enlargements (or dilations) will create similar shapes.
Difference between similar triangles and congruent triangles?
Similar triangles are two triangles with three identical angles but not necessarily identical lengths but if they aren't identical they must have an identical scale factor for each side. Congruent triangle have identical angles and lengths but mat be rotated. on a similar triangle if one size gets bigger by two times the original all of them must be two times the original.
Are two equilateral triangles sometimes always or never similar to each other?
Since triangles have three sides and must have interior angles equal to pi or 180o, the three interior angles in all equilateral triangles will be pi/3 or 60o.However, equilateral triangles must also have equal side lengths. Since equilateral triangles with interior angles of 60o will not necessarily have the same side lengths, two equilateral triangles will sometimes be similar to each other.
Are all isosceles right triangles congruent?
Yes- but not all isosceles triangles are right triangles. Isosceles means that two sides are the same length, and two angles are the same.
Two right triangles that are not similar still may have one congruent acute angle in common?
Not so. The two acute angles of a right triangle must add up to 90 degrees.So if the triangles have one congruent acute angle in common, they must alsohave the other acute angle in common, and then they're similar.
Will the lengths of two corresponding altitudes of similar triangles will have the same ratio as any pair of corresponding sides?
It is given that two triangles are similar. So that the ratio of their corresponding sides are equal. If you draw altitudes from the same vertex to both triangles, then they would divide the original triangles into two triangles which are similar to the originals and to each other. So the altitudes, as sides of the similar triangles, will have the same ratio as any pair of corresponding sides of the original triangles.
Two isosceles triangles are similar if?
Any one pair of their corresponding angles are equal.
How you can prove that the angles of two triangles are equal?
If the angles of two triangles are equal the triangles are similar. AAA If you have three angles on both triangles these must be equal for the triangles to be similar. SAS If you have an angle between two sides and the length of the sides and the angle are the same on both triangles, then the triangles are similar. And SSS If you know the three sides
What composition of transformations will create a pair of similar not congruent triangles?
Enlargements (or dilations) will create similar shapes.
Are congruent triangles similar?
Yes, similar triangles are congruent because in order to be congruent they must first be equal. Which in turn is the definition of a similar triangle. A triangle equal in angle measurements and/or side lengths. So, yes.
Are two triangles always the similar?
Nope. You must know what it means to be similar. It means that ALL three angles are the same between two triangles. That been said, you can take any two random triangles, it's very likely that they are NOT similar.
What are three ways you can prove that triangles are similar?
Two triangles are similar if:two pairs of corresponding angles are equal, orone pair of angles is equal, and the ratios of the lengths of sides adjacent to the angles are the same, orthe lengths of the three pair of corresponding sides are in the same ratio.For the first point, if two angles of one triangle are equal to two of the other, then the third angles = 180 - sum of the two, must be equal.
Similar triangles must have congruent angles and congruent sides?
False dood
To use the HL theorem to prove two triangles are congruent the triangles must be right trianglesWhich other conditions must also be met?
1. There are two right triangles. 2. They have congruent hypotenuses. 3. They have one pair of congruent legs.
Are similar triangles always congruent?
No, congruent triangles are always similar but similar triangles and not always congruent. Imagine that similar triangles can be created on a copy machine enlarge and shrink the image, turn it, even turn it over, the angles remain the same. A congruent triangle must be exactly the same as the original. Hope this helps!
What else must be true about the sides of the triangles in order for the triangles to be similar?
All three ratios of a side of one triangle to the corresponding side of the other triangle must be the same.
Difference between similar triangles and congruent triangles?
Similar triangles are two triangles with three identical angles but not necessarily identical lengths but if they aren't identical they must have an identical scale factor for each side. Congruent triangle have identical angles and lengths but mat be rotated. on a similar triangle if one size gets bigger by two times the original all of them must be two times the original.
