What 3d shape has 4 congruent triangles?
A tetrahedron has four equilateral triangles as sides
If triangles are congruent they have the same?
If the triangle is the same size, and it's sides are congruent to the other, then yes they are congruent to each other.
What does non congruent mean?
In geometry two figures are congruent if they have the same shape and size if they are non congruent they do not have the same shape and size two triangles are congruent if their corresponding sides are all equal in lengh and their corresponding angles are equal in size
If six equilateral triangles are placed side by side so that only two sides of each triangle touch one of the other triangles what shape is formed?
Parellelogram
What shape has four congruent sides and four congruent angles?
A square, because congruent means equal.
What congruent shape can 2 right-angled triangles make?
Isosceles triangle
What figure is formed when you put two congruent triangles together?
Figure that are congruent are shapes are the same size and shape. So when two formed congruent triangles are both together they fit just right.
Are all isosceles right triangles congruent?
Yes- but not all isosceles triangles are right triangles. Isosceles means that two sides are the same length, and two angles are the same.
Simone has a regular 5- sided shape ans 5 congruent acute isosceles triangles what solid figure can she construct?
rectangle
Can all 4 sided shape be made by two right angled triangles?
Absolutely. Any two congruent right triangles will form a rectangle, and if the right triangles are isosceles right triangles, they will form a square.
What other 2d shape has congruent triangles in it?
A square and rectangle both have congruent triangles in them.
What do you call triangles that are the same size and shape?
congruent triangles
What shape is formed using 5 congruent triangles and has 5 vertices 5 angles 5 sides?
pentagon
What shape is made out of two congruent triangles?
If you have 2 EQUILATERAL triangles, and you stack them on their respective hypotenuses, the result: SQUARE. If you have 2 ISOSCELES triangles, and you stack them on their respective hypotenuses, the result: RECTANGLE. If you have 2 OBTUSE triangles, and you stack them on their respective hypotenuses, the result: PARALLELOGRAM.
What shape has four faces that are isosceles triangles?
tetrahedron
How would you prove triangles are congruent?
You could prove two triangles are congruent by measuring each side of both triangles, and all three angles of each triangle. If the lengths of the sides are the same, and so are the angles, then the triangles are congruent... if not, then the triangles are not congruent. If the triangles have the exact same size and shape then they are congruent.
Congruent triangles have what the same?
shape and sizecorresponding sides
