Question

Which statement is correct?


1. Triangle 1 is a right triangle and Triangle 2 is an acute triangle.
2. Triangle 2 is an obtuse triangle and Triangle 3 is a right triangle.
3. Triangle 1 is a right triangle and Triangle 3 is an obtuse triangle.
4. Triangle 1 is a right triangle and Triangle 3 is an acute triangle.

Answer 1

Pictures would be more convenient.

Answer 2

Triangle 1
45°, 45°, 90°
Triangle 2
30°, 110°, 40°
Triangle 3
24°, 76°, 80°

Answer 3

4th one is correct. Triangle 1 is right (because one angle is 90) and triangle 3 is acute(because all three angles are acute).

Answer 4

thanks :)

Answer 5

welcome

Answer 6

As part of constructing an isosceles triangle, Gail drew a line segment and plotted one vertex of the triangle on the line segment. With this vertex as the center, Gail drew an arc to create a 180 degree angle. How can Gail ensure that the two other points she plots will be the remaining two vertices of an isosceles triangle?

Answer 7

1.Plot both the points on the arc.
2.Plot both the points on the line segment.
3.Plot one point on the arc and the other beyond the arc.
4.Construct a perpendicular line and plot one point on the perpendicular line and the other inside the arc.
