What is a tetrahedral in Chemistry?
A tetrahedron is a four-sided platonic solid constructed by connecting four triangles along their sides. The four corners of this figure can be compared to the electron bonding positions on an atom with four bonds or electron pairs, such as ammonia or methane.
Which of these statements describe properties of parallelograms?
Opposite sides are parallel, Consecutive angles are supplementary, Opposite angles are congruent, Opposite sides are congruent (APEX)
What are four chracteristics of sodium?
what are four chracteristics of sodium
What does the four in the chemical formula CH4 mean?
The four means that there are four atoms of hydrogen bonded to the carbon atom, and that compound is methane.
What are the four steps of the oxidation number?

How can you remove 4 toothpicks from 16 toothpicks to get 4 congruent triangles?
Fuor toothpicks from 16 leave 12 which, by coincidence (?) is exactly enough for four equilateral triangles!
Can you arrange eight toothpicks so they form two squares and four triangles without breaking any toothpicks?
no
What 3d shape has 4 congruent triangles?
A tetrahedron has four equilateral triangles as sides
Use 9 toothpicks to form 3 squares each side of which is a complete toothpick length?
Firstly, take out three toothpicks that form a triangle. You will be left with two triangles. Secondly, place all three toothpicks to form a triangle above the centre of the two triangles. Four small triangles and a large triangle will be formed, which makes them five triangles. Example: At first: /_\/_\/_\ Imagine that these are three triangles (nine toothpicks), with the sides joined. Secondly: /_\/_\ Imagine that you have taken away one triangle (three toothpicks). Thirdly: Place the three toothpicks to form a triangle above the two triangles. Imagine that the sides are joined. Four small triangles are formed. The four triangles make up a large triangle, which makes them five. /_\ /_\/_\
What is the name of the geometric solid with four faces that are congruent triangles?
Isosceles TetrahedronA solid with four faces is a tetrahedron. Each of the faces is a triangle. If all the triangles are congruent, you have an isosceles tetrahedron.
How many pairs of congruent triangles are formed diagonals of a rectangle?
Four.
What trapezoid can be subdivided into four congruent right triangles?
An isosceles trapezoid can be subdivided into 4 right angle triangles.
What are the four congruence theorems for a right triangle?
The four congruence theorem for right triangles are:- LL Congruence Theorem --> If the two legs of a right triangle is congruent to the corresponding two legs of another right triangle, then the triangles are congruent.- LA Congruence Theorem --> If a leg and an acute angle of a right triangles is congruent to the corresponding leg and acute angle of another right triangle, then the triangles are congruent.- HA Congruence Theorem --> If the hypotenuse and an acute angle of a right triangle is congruent to the corresponding hypotenuse and acute angle of another triangle, then the triangles are congruent.- HL Congruence Theorem --> If the hypotenuse and a leg of a right triangle is congruent to the corresponding hypotenuse and leg of another right triangle, then the triangles are congruent.
Which type of quarilateral has diagonals that will always divide it into four congruent triangles?
Only the square has.
What are the four congruence theorem for right triangle?
four types aressssasrhsasa1.HyL Theorem (Hypotenuse-Leg) - if the hypotenuse and leg of one triangle is congruent to another triangle's hypotenuse and leg, then the triangles are congruent.2.HyA (Hypotenuse-Angle) - if the hypotenuse and angle of one triangle is congruent to another triangle's hypotenuse and angle, then the triangles are congruent.3.LL (Leg-Leg) if the 2 legs of one triangle is congruent to another triangle's 2 legs, then the triangles are congruent.4.LA (Leg-Angle) if the angle and leg of one triangle is congruent to another triangle's angle and leg, then the triangles are congruent.
How can you form four equilateral triangles with six toothpicks of equal length?
Think in 3-dimensions and make a tetrahedron (a triangular pyramid).
Can two triangles be congruent with 5 pairs of congruent parts?
Two triangles are congruent if the six elements of one triangle (three sides and three angles) are equal to the six elements of the second triangle and the two triangles have a scale factor of 1. However, in four special cases it is only necessary to match three elements to prove that two triangles are congruent. The matching of four elements is sometimes necessary, and the matching of five elements would put the matter beyond any doubt.
