How to know if a triangle is obtuse or acute
WebIn an obtuse triangle, one of the angles of the triangle is greater than 90°, while in an acute triangle, all of the angles are less than 90°, as shown below. Triangle facts, theorems, and laws. It is not possible for a triangle to have more than one vertex with internal angle greater than or equal to 90°, or it would no longer be a triangle. Web7 mrt. 2024 · IF the sum of squares of the 2 shortest sides > the square of the longest side, the triangle is acute a 2 + b 2 > c 2 IF the sum of squares of the 2 shortest sides < square of the longest side, it's an obtuse triangle a 2 + b 2 < c 2 This can be seen from the law of cosines c 2 = a 2 + b 2 - 2abcosC

WebDetermine whether a triangle with sides 8 cm, 15 cm and 17 cm is an acute, right or obtuse triangle. Solution: We choose the two shorter sides to be a and b and the longest side to be c. So a = 8, b = 15 and c = 17. a 2 + b 2 = 8 2 + 15 2 = 64 + 225 = 289 c 2 = 17 2 = 289 289 = 289 → c 2 = a 2 + b 2, and so the triangle is an right triangle.

WebRT @KelleyKga: I'm still mad about this today. 🤬How can we expect kids to learn and succeed when teachers and curriculum provide INCORRECT information? This one math problem has both a misspelled homophone (weather/whether), and a 180* angle that isn't acute, right, or obtuse (it's straight).
WebYes, ∠A is acute angle. When x = 65°: 65 < 90 Yes, ∠A is acute angle. When x= 90° 90 < 90 (not true) Alternatively, 90 = 90 So, ∠A is not acute if x = 90°. When x = 135°: 135 < 90 (not true since 135 > 90) So, ∠A is not acute if x = 135°. Example 2: Which angle is right? Acute?
