Right Isosceles triangle Isosceles triangle 45º Right scalene triangle right triangle 45º Check all the characteristics that are true about thegiven triangle. (hint: there are 4) acute triangle obtuse triangle right triangle equiangular triangle equilateral triangle Isosceles triangle scalene triangle What is always true aboutangles ∡A and ∡B for the given right triangle. a. They are acute. b. They add to 90 degrees. c. They are congruent. d. Both a. and b. are correct. A B C Use the distance formula to find AB, BC, and AC. Classify the triangle by its side lengths. Scalene, because AC ≠ AB ≠ BC. Isosceles, because BC = AC. Isosceles, because AC = AB. Equilateral, because AC = AB = BC. Use the distance formula to find AB, BC, and AC. Classify the triangle by its side lengths. Scalene, because AC ≠ AB ≠ BC. Isosceles, because AC = AB. Isosceles, because BC = AB. Equilateral, because AC = AB = BC. |
