The solution to problem from the 5th-grade mathematics textbook by E.A. Bunimovich (from the "Spheres" series) involves identifying types of triangles based on their angles or sides. Problem Condition
Does your textbook show specific degree measurements for these triangles, or

is typically right-angled (it has a square corner marker).
Usually, problem 329 asks you to determine the type of triangle shown in a figure or described by its angles/sides. For the standard edition, the task is: The solution to problem from the 5th-grade mathematics
If one leans back, a lazy wide, is where the shadows hide.But if they all stay sharp and small, Acute is the cutest of them all!
is typically obtuse-angled and isosceles (one wide angle and two equal sides). Triangle v) is typically acute-angled . is typically right-angled (it has a square corner marker)
1. Identify angle types First, look at the largest angle in each triangle: If the largest angle is less than 90∘90 raised to the composed with power , the triangle is acute . If one angle is exactly 90∘90 raised to the composed with power , the triangle is right-angled . If one angle is greater than 90∘90 raised to the composed with power , the triangle is obtuse . 2. Identify side types Next, check the lengths of the sides: If two sides are equal , the triangle is isosceles . If all three sides are equal , the triangle is equilateral . If no sides are equal , the triangle is scalene . 3. Record the result According to the textbook diagrams for exercise 329:
