Triangle similarity is another relation two triangles may have. We already learned about congruence, where all sides must be of equal length. Two triangles are similar if the lengths of two corresponding sides are proportional and their corresponding angles across the larger of these two are congruent.
Given a triangle, find the minimum path sum from top to bottom. Each step you may move to adjacent numbers on the row below. Bonus point if you are able to do this using only O(n) extra space, where n is the total number of rows in the triangle.
Generally, two triangles are said to be similar if they have the same shape, even if they are scaled, rotated or even flipped over. Following the same explanation provided in the examples above, we can conclude that the two triangles ΔABC and ΔADE are similar.
6.6 Application of Similar Triangles 8.A 1 The lesson uses similar triangles to determine indirect measurements. Students will set up proportions to solve problem situations. x x 600011_TIG_CH06_513-598.indd 2 15/07/14 11:54 PM
It was learned earlier in Lesson 4 that the slope of the line on a velocity versus time graph is equal to the acceleration of the object. If the object is moving with an acceleration of +4 m/s/s (i.e., changing its velocity by 4 m/s per second), then the slope of the line will be +4 m/s/s.
A triangle that has one obtuse angle is called an obtuse triangle. When a triangle has three congruent sides, we call the triangle an equilateral triangle. We mark the congruent sides by a slash mark. The angles in an equilateral triangle are always 60°. When a triangle has two congruent sides it is called an isosceles triangle.

Similar triangles have equal corresponding angles, and so do congruent triangles. Triangles are congruent if all three sides in one triangle are congruent to the corresponding sides in the other.When two triangles have corresponding sides with identical ratios, the triangles are similar.Of course if...
