WebJan 25, 2024 · Ans: Classification of triangles are based on the measure of their angles and sides: a) Based on side lengths: equilateral triangle, scalene triangle, and isosceles triangle. b) Based on angle measures: acute-angled triangle, right-angled triangle, right-isosceles triangle, obtuse-angled triangle. Q.3. WebUsing the first equation replace x 2 + h 2 by c 2 then using the third equation replace x by a - b cos (C). Simplify to get. c 2 = a 2 + b 2 - 2ab cos (C) This is the Law of Cosines. If you know the side lengths a, b and c you can find cos (C) and hence the measure of the angle C. Harley. Hi Lucy. Here's an example of how I would use Harley's ...

WebJul 2, 2024 · Any triangle in which the Euler line is parallel to one side is an acute triangle. Acute triangles can be isosceles, equilateral, or scalene. The longest side of an acute triangle is opposite the largest angle. Acute … WebApr 7, 2024 · It is also referred to as an equiangular triangle. Based on the interior angles, triangles are classified into three types, they are: Acute angle triangle. Obtuse angle triangle . Right angle triangle. Acute Angle Triangle. A triangle where all three interior angles are less than 90 degrees is called an acute-angled triangle. Obtuse Angle Triangle WebThere are three types of triangle based on the length of the sides: equilateral, isosceles, and scalene. The green lines mark the sides of equal (the same) length. A triangle’s name also depends on the size of its inside angles: acute if all angles are less than 90°, right-angled if one angle is 90°, or obtuse if one angle is more than 90°. pelvic gas pain in men
