To determine its perimeter, find the sum of all the side lengths of the park. 90 + 60 + 40 = 190 Hence, the perimeter of the triangular park is 190 meters. Example 3: Classify the triangle based on its angles. Solution: From the figure, angles of the triangle are 36 degrees, 54 degrees and 90 degrees.

What types of triangles have at least two congruent sides?

WebAngles: 30°: 60°: 90° Ratio of sides: 1:√ 3 :2 Side lengths: a:5:c Then using the known ratios of the sides of this special type of triangle: a = b √ 3 = 5 √ 3 c = b × 2 √ 3 = 10 √ 3 As can be seen from the above, knowing just one side of a 30°-60°-90° triangle enables you to determine the length of any of the other sides relatively easily. WebNow, to find the measure of the other angle, we add the known angles and subtract from 180°. Therefore, we have: 70°+70° = 140° ⇒ 180°-140° = 40° The measure of angle a is 40°.
