A triangle with interior angles that each measure less than 90° is called an acute triangle. In an acute triangle, all three angles are less than 90°.
To understand this concept, let's look at an example. Imagine a triangle with angle A measuring 60°, angle B measuring 50°, and angle C measuring 70°. In this triangle, all three angles are less than 90°, so it is an acute triangle.
Acute triangles have some interesting properties. Since the angles are all less than 90°, the sides opposite these angles are also shorter in length compared to the sides of a right triangle or an obtuse triangle. Additionally, acute triangles have the following properties:
1. The sum of the measures of the interior angles is always 180°.
2. The longest side is always opposite the largest angle, while the shortest side is opposite the smallest angle.
3. The altitude from any vertex lies inside the triangle.
4. The circumcenter, which is the center of the circle passing through all three vertices, lies inside the triangle.
Understanding the concept of acute triangles is important in geometry, as it helps in solving various problems related to triangles and their properties.

2) what glacial features formed the north shore beaches?
3).what glacial features formed the south shore beaches?
Answer:
B. Russia
Explanation:
Russia will be mostly affected if the international environmental policies encourages the reduction of reliance on fossil fuels such as coal, crude oil, gas, coal .Russia has one of the highest crude oil reserves and also one of the highest producer of oil.
Russiaeconomy is highly dependent on the export of crude oil and it major market is Europe.Russia also have a large market for coal too because it has large deposit of this natural resource.
Therefore, any attempt to reduce reliance on fossil fuel will affect Russia economy more and cause unemployment.
Answer: 5
Explanation:
-faults and folds
-intrusive and extrusive igneous rocks
-volcanic necks
-flood basalt plateaus
-calderas and craters
-anticlines and synclines
The correct answers are:
- intrusive and extrusive igneous rocks;
These types of rocks are a direct result of the magma/lava, and they are created at different depths, depending on the place where the magma/lava hardens.
- volcanic necks;
The volcanic neck forms into a vent or an active volcano when a magma hardens inside it. After some time, when the erosive processes take action and weather the surrounding area, they remain as stick out neck-like objects.
- flood basalt plateaus;
The flood basalt plateaus form when the lava that came on the surface manages to create a pool of lava in the landscape and after that it hardens. So after the erosive processes take place they stick out in the surrounding area as little plateaus.
- calderas and craters;
They represent a pale version of the shape of the once active volcano, and give as u picture of their appearance when they were at their peak. They have cone shape and usually stick out significantly in the surrounding are.
Answer:
Erosion affects waterways in different manners. If it is high, particles produced by erosion go to river banks or river beds. Many places will be under water if there´s a flood. Erosion also may affect river navigation because it can cause deposits of solid particles that alter a canal´s depth or shape.
